Description

  The present invention relates to a printer system that includes a printer and an external device that is communicably connected to the printer. In particular, the present invention relates to a printer system that performs printing based on print data including an address of a DL object (an object that needs to be downloaded from outside).

  For example, Patent Document 1 below discloses a printer system that performs printing based on XML-format print data. When the printer receives the XML format print data, the printer transmits the print data to the server. The server downloads document data by accessing a URL (Uniform Resource Locator) included in the print data. The server creates print data in SVG format that includes the downloaded document data. That is, the server converts XML format print data into SVG format print data. The server transmits SVG format print data to the printer. The printer prints based on the print data in the SVG format.

  When a DL object is downloaded from outside and printed, it is necessary to apply various transformation processes to the DL object. For example, a resizing process for resizing to a printable size may have to be added to the DL object. Further, for example, a rotation process for rotating from a downloaded state to a specified state may be applied to the DL object. In order to execute these deformation processes, a large memory capacity is required. A printer does not have a large-capacity memory as compared with a personal computer or the like. For this reason, if a large amount of memory capacity is consumed to execute the deformation process for the DL object, it may not be possible to secure a memory capacity for executing other processes.

  The present inventor has noted that a printer is often connected to an external device (for example, a personal computer or a server) so as to be communicable. By causing the external device to execute transformation processing on the DL object, it is possible to prevent an event that the printer memory is consumed significantly. When this method is used, the printer needs to send print data to an external device, and the external device needs to send the processed print data back to the printer. In the technique of the above cited reference 1, the printer transmits XML format print data to an external device (server), and the external device returns SVG format print data to the printer. That is, the data format transmitted from the printer to the external device is different from the data format returned from the external device to the printer. For example, a plurality of printers may be used by being connected to an external device so as to be communicable. In this case, each printer transmits print data to an external device, and the external device returns SVG format print data to each printer. Not all printers are compatible with the SVG format. Even if the external device returns print data in the SVG format to each printer, a printer that does not support the SVG format cannot print. That is, the external device needs to return the print data to the printer in a format that allows the printer to continue the print processing based on the print data received from the external device.

  The present specification provides a technique that allows a printer to print print data after deformation processing in a printer system in which an external device executes deformation processing of a DL object.

  One technique disclosed in this specification is a printer system including a printer and an external device. The printer can print based on print data in a predetermined format including the address of a DL object that needs to be downloaded from the outside. The external device is communicably connected to the printer. The term “external device” is to be interpreted in the broadest sense, and is a concept that includes all devices configured separately from the printer. Examples of the external device include a personal computer, a server, a printer, a scanner, a multi-function device (multifunction device), and a portable terminal.

  The printer includes a printer-side first receiving unit, a printer-side transmitting unit, a printer-side second receiving unit, and a printing unit. The first receiving unit on the printer side receives the print data in the predetermined format. The printer-side transmission unit transmits the print data in the predetermined format received by the printer-side first reception unit to the external device. The printer-side second receiving means receives the post-deformation-processed print data of the predetermined format transmitted from the external device. The printing means prints based on the post-deformation processed print data in the predetermined format received by the printer-side second receiving means.

  The external apparatus includes an external apparatus side receiving unit, a deforming unit, a post-deformation print data creating unit, and an external apparatus side transmitting unit. The external device side receiving means receives the print data of the predetermined format transmitted from the printer. The transformation means creates a post-deformation DL object by performing transformation processing on the DL object downloaded according to the DL object address included in the print data in the predetermined format received by the external device side reception means. To do. The download of the DL object may be executed by a printer or an external device. In the former case, the printer-side transmission unit transmits both the print data and the DL object to the external device. The post-deformation print data creation unit creates the post-deformation print data of the predetermined format by writing the post-deformation DL object created by the deformation unit into the print data of the predetermined format. The external device side transmission means transmits the post-deformation print data in the predetermined format created by the post-deformation print data creation means to the printer.

  Even if the printer receives print data in a format that it does not support (a format that it cannot print), it cannot interpret the contents. Even if the printer receives print data whose contents cannot be interpreted, it cannot execute a process of transmitting the print data to an external device. In other words, if the print data is in the same format as the print data received by the printer and transmitted to the external device, the printer can interpret the content and print it. In the printer system described above, the format of the print data before the deformation process received by the printer and transmitted to the external device matches the format of the print data after the deformation process created by the external device. For this reason, the printer can print based on the post-deformation print data. According to the above printer system, the printer can surely print based on the post-deformation print data created by the external device.

  As described above, the download of the DL object may be executed by a printer or an external device. In order to prevent the use of a large-capacity memory in the printer, it is preferable to adopt the latter configuration. This configuration can be expressed as follows. In other words, the external device may further include a download unit that downloads the DL object in accordance with the address of the DL object included in the print data in the predetermined format received by the external device side receiving unit. In this case, the deformation means creates a post-deformation DL object by performing a deformation process on the DL object downloaded by the download means.

If the print data received by the printer does not include the address of the DL object, there is no need to apply transformation processing to the DL object. In this case, the printer does not have to send print data to the external device. According to this configuration, the printer can execute print processing without sending print data to an external device and waiting for it to be returned. For this reason, the printing process can be executed at high speed. This configuration can be expressed as follows.
That is, the printer may further include first determination means for determining whether or not the DL object address is included in the print data of the predetermined format received by the printer-side first reception means. . In this case, the printer-side transmission unit may transmit the print data in the predetermined format to the external device on condition that the first determination unit makes a positive determination.

  Even when the address of the DL object is included in the print data, the transmission of the print data from the printer to the external device may be prohibited if other conditions are satisfied. Thereby, for example, speeding up of the printing process can be realized. For example, the printer may further include a second determination unit that determines whether it is necessary to apply deformation processing to the DL object. In this case, the printer-side transmission unit may transmit the print data in the predetermined format to the external device on the condition that the determination is positive by the second determination unit. The second determination unit may determine whether it is necessary to add at least one of rotation processing and resizing processing to the DL object.

  Even when a negative determination is made by the second determination unit, the print data may be transmitted from the printer to the external device if other conditions are satisfied. For example, the printer may further include third determination means for determining whether or not the data size of the DL object is equal to or larger than a predetermined size. In this case, the printer-side transmission unit transmits the print data in the predetermined format to the external device on the condition that the determination is negative by the second determination unit and the determination by the third determination unit is affirmative. May be sent to. In this case, the external device may further include a download unit that downloads the DL object in accordance with the address of the DL object included in the print data in the predetermined format received by the external device side receiving unit. Further, the external device creates the post-write print data in the predetermined format by writing the DL object into the print data in the predetermined format without applying any transformation process to the DL object downloaded by the download unit. You may further have an after-printing print data preparation means. In this case, the external apparatus-side transmission unit may transmit the post-write print data in the predetermined format created by the post-write print data creation unit to the printer. The second receiving unit on the printer side may receive the print data after writing in the predetermined format transmitted from the external device. The printing unit may print based on the post-write print data in the predetermined format received by the printer-side second receiving unit.

A computer program for realizing the above external device is also useful. This computer program causes a computer mounted on an external device to execute the following processing.
(1) Deformation processing for creating a post-deformation DL object by applying a deformation process to the DL object downloaded according to the DL object address included in the print data of a predetermined format transmitted from the printer.
(2) Post-deformation print data creation processing for creating post-deformation print data in the predetermined format by writing the post-deformation DL object created in the deformation processing into the print data in the predetermined format.
(3) Transmission processing for transmitting the post-deformation print data in the predetermined format created in the post-deformation print data creation processing to the printer.
According to this computer program, it is possible to realize an external device that constitutes the printer system.

Here, some of the main features of the techniques described in the following examples are summarized.
(Mode 1) The post-deformation print data creation unit converts the post-deformation post-transformation DL object created by the transformation unit into text format data, and writes the converted data into the predetermined format print data. But you can.

(Mode 2) The second determining means determines whether or not it is necessary to apply a deformation process to the DL object based on the content of the print data in the predetermined format received by the printer-side first receiving means. May be. For example, the second determination unit needs to apply a rotation process to the DL object based on the rotation angle information of the DL object included in the print data of the predetermined format received by the printer-side first reception unit. It may be determined whether or not. In addition, for example, the second determination unit needs to apply a resizing process to the DL object based on the print size information of the DL object included in the print data in the predetermined format received by the printer-side first receiving unit. It may be determined whether or not there is. The “DL object print size information” means the data size (vertical and horizontal sizes) when the DL object is printed on a print medium.

(Mode 3) The print data in the predetermined format may include an address of a file including the rotation angle information of the DL object. The printer may further include means for downloading the file in accordance with the address of the file included in the print data of the predetermined format. In this case, the second determination means may determine whether or not it is necessary to apply a rotation process to the DL object based on the rotation angle information of the DL object included in the downloaded file.

(Mode 4) The print data in the predetermined format may include an address of a file including print size information of the DL object. The printer downloads the file according to the address of the file included in the print data of the predetermined format, and downloads the absolute size information of the DL object according to the address of the DL object included in the print data of the predetermined format. It may further have a means to do. In this case, the second determination means needs to apply a resizing process to the DL object by comparing the print size information of the DL object included in the downloaded file with the absolute size information of the downloaded DL object. It may be determined whether or not there is. Note that the above “absolute size information of DL object” means the data size (vertical and horizontal size) of the DL object in the state stored in the DL object address (for example, stored in the server).

  Embodiments will be described with reference to the drawings. FIG. 1 shows a printer system 2 of this embodiment. The printer system 2 includes a plurality of printers 10, 30, 40, a server 50, and a PC (personal computer) 70.

(Printer configuration)
The printer 10 includes an operation unit 12, a display unit 14, a control unit 16, a printing unit 18, a storage unit 20, and an input / output port 22. The operation unit 12 includes a plurality of keys. The user can input various information and instructions to the printer 10 by operating the operation unit 12. The display unit 14 can display various information. The control unit 16 executes various processes according to the program stored in the storage unit 20. Details of processing executed by the control unit 16 will be described in detail later. The printing unit 18 can print various data according to instructions from the control unit 16. The storage unit 20 is configured by a ROM, an EEPROM, a RAM, and the like. The storage unit 20 stores a program for causing the control unit 16 to execute processing. The storage unit 20 can store data input to the input / output port 22 and data generated by the control unit 16. The input / output port 22 is connected to the LAN 45. The printer 10 can communicate with the server 50 and the PC 70 via the input / output port 22 and the LAN 45. The printers 30 and 40 have the same configuration as the printer 10. For this reason, the description of the printers 30 and 40 is omitted.

(Server configuration)
The server 50 includes an operation unit 52, a display unit 54, a control unit 56, a storage unit 60, and an input / output port 62. The operation unit 52 includes a mouse and a keyboard. The user can input various information and instructions to the server 50 by operating the operation unit 52. The display unit 54 can display various information. The control unit 56 executes various processes according to the program stored in the storage unit 60. The contents of the processing executed by the control unit 56 will be described in detail later. The storage unit 60 includes a ROM, an EEPROM, a RAM, and the like. The storage unit 60 stores a program for causing the control unit 56 to execute processing. The storage unit 60 can store data input to the input / output port 62 and data generated by the control unit 56. The input / output port 62 is connected to the LAN 45. The server 50 can communicate with the printers 10, 30, 40 and the PC 70 via the input / output port 62 and the LAN 45.

(Printing process of printer)
Next, the contents of print processing executed by the printer 10 will be described. This process is executed by the control unit 16 of the printer 10. The other printers 30 and 40 can execute the printing process in the same manner as the printer 10. FIG. 2 shows a flowchart of the printing process. The printing process is started when the print data transmitted from the PC 70 is received.

  The printer 10 receives print data from the PC 70 (S10). The printer 10 determines whether it is XHTML-Print data by analyzing the contents of the print data (S12). If the print data is in a format other than XHTML (NO in S12), the process proceeds to S32. On the other hand, if the data is XHTML-Print data (YES in S12), the process proceeds to S14. Hereinafter, the XHTML-Print data may be simply referred to as “XHTML data”.

  FIG. 3 shows an example of XHTML data. The XHTML data 80 includes a style sheet file address 82 and an image object file address 84. Although not shown, the XHTML data 80 includes the base address of the style sheet file. The style sheet file address is specified by a combination of a base address and an address 82. The printer 10 determines whether or not the stylesheet file address 82 is included in the XHTML data received in S10 (S14). If YES here, the printer 10 accesses the address 82 and downloads the style sheet file (S16). Specifically, the printer 10 instructs the device specified from the base address (not shown) to transmit the style sheet file specified from the address 82. As a result, the printer 10 can acquire the style sheet file.

  FIG. 4 shows an example of a style sheet file. The style sheet file 90 includes print size information 92 and rotation angle information 94 of the image object. The print size information 92 means a data size (vertical / horizontal size) when an image object is printed on a print medium. In the example of FIG. 4, it means that printing is performed with a size of 20 mm in length and 20 mm in width. The rotation angle information 94 means a rotation angle when the image object is printed on the print medium. That is, it means how many times the image object is printed from the state stored in the external network (for example, address 84). In the example of FIG. 4, it means that printing is performed by rotating 90 degrees clockwise.

  FIG. 5 shows another example of XHTML data. The XHTML data 100 does not include the address of the style sheet file. In this case, the printer 10 determines NO in S14. In this case, S16 is skipped. The XHTML data 100 includes print size information 102 and rotation angle information 104. That is, the print size information 102 and the rotation angle information 104 are described in the XHTML data 100. The XHTML data 100 includes an address 106 of the image object file.

  The printer 10 determines whether or not the address of the image object file is included in the XHTML data (S18). For example, the XHTML data 80 in FIG. In this case, YES is determined in S18. Also, the XHTML data 100 in FIG. Also in this case, YES is determined in S18. If YES is determined in S18, the process is included in S20. On the other hand, if NO is determined in S18, the process proceeds to S32.

  In S20, the printer 10 determines whether or not it is necessary to apply rotation processing to the image object. As described above, the rotation angle information may be described in the style sheet file or may be described in the XHTML data. In the former case, the printer 10 determines whether or not the rotation angle information 94 included in the style sheet file 90 is zero. In the latter case, the printer 10 determines whether the rotation angle information 104 included in the XHTML data 100 is zero. If the rotation angle information is zero, the printer 10 determines NO in S20. In this case, the process proceeds to S22. If the rotation angle information is a numerical value other than zero, the printer 10 determines YES in S20. In this case, the process proceeds to S28.

  In S22, the printer 10 downloads the header information of the image object file. Specifically, the printer 10 sends the header information (information from the beginning to a predetermined byte) of the image object file specified from the addresses 84 and 106 to the device specified from the addresses 84 and 106 of the image object file. Instruct to send. Thereby, the printer 10 can acquire the header information of the image object file. The header information of the image object file includes absolute size information of the image object. The absolute size information means the data size (vertical / horizontal size) of the image object stored in an external network (for example, address 84 or 106). When S22 ends, the process proceeds to S24.

  In S24, the printer 10 determines whether or not it is necessary to apply a resizing process to the image object. As described above, the print size information may be described in the style sheet file or may be described in the XHTML data. In the former case, the printer 10 determines whether the print size information 92 included in the style sheet file 90 matches the absolute size information downloaded in S22. In the latter case, the printer 10 determines whether the print size information 102 included in the XHTML data 100 matches the absolute size information downloaded in S22. If the print size information matches the absolute size information, the printer 10 determines NO in S24. In this case, the process proceeds to S26. If the print size information does not match the absolute size information, the printer 10 determines YES in S24. In this case, the process proceeds to S28.

  In S26, the printer 10 determines whether or not the absolute size information downloaded in S22 is larger than a predetermined byte. As this “predetermined byte”, various numerical values can be adopted. For example, a preset value may be adopted as the “predetermined byte”. For example, the “predetermined byte” may be set based on the free capacity of the storage unit 20. When the free space of the storage unit 20 is large, the “predetermined byte” may be large, and when the free space of the storage unit 20 is small, the “predetermined byte” may be small. If the absolute size information is larger than the predetermined byte, the printer 10 determines YES in S26. In this case, the process proceeds to S28. On the other hand, if the absolute size information is smaller than the predetermined byte, the printer 10 determines NO in S26. In this case, the process proceeds to S32.

  In S <b> 28, the printer 10 transmits the XHTML data 80 and 100 to the server 50. When the style sheet file 90 is downloaded in S <b> 16, the printer 10 also transmits the style sheet file 90 to the server 50. By executing the process of S28, the process described later is executed by the server 50. Details of processing executed by the server 50 will be described later in detail. The server 50 transmits the processed XHTML data 80 and 100 to the printer 10. The printer 10 receives the processed XHTML data 80 and 100 (S30).

  Finally, the printer 10 executes a printing process (S30). For example, if NO is determined in S12, the printer 10 executes rasterization processing based on print data in a format other than XHTML data to create bitmap data, and prints based on the bitmap data. Further, for example, if NO is determined in S18, the printer 10 executes rasterization processing based on the XHTML data, creates bitmap data, and prints based on the bitmap data. In this case, the image object is not printed, and only text data is printed, for example. This is because the address of the image object is not included in the XHTML data. For example, if NO is determined in S26, the printer 10 performs printing based on the XHTML data. In this case, the printer 10 downloads the image object according to the address included in the XHTML data. The printer 10 performs rasterization processing on the downloaded image object to create bitmap data, and prints based on the bitmap data. For example, when S30 is executed, the printer 10 executes rasterization processing based on the XHTML data received in S30 to create bitmap data, and prints based on the bitmap data. In this case, the printer 10 does not need to download an image object. This is because the image object is downloaded by the server 50 and written in the XHTML data (XHTML data received in S30), as will be described later.

(Server processing)
Next, the contents of processing executed by the server 50 will be described. This process is executed by the control unit 56 of the server 50. FIG. 7 shows a flowchart of processing executed by the server 50. This process is started when the XHTML data transmitted from the printer 10, 30, 40 is received. That is, the process is started when the printer 10 or the like executes the process of S28 of FIG.

  The server 50 receives XHTML data from the printer 10 or the like (S40). Next, the server 50 executes a writing process (S42). The writing process will be described in detail later. The server 50 returns the XHTML data after the writing process of S42 to the printer 10 or the like. As a result, the printer 10 or the like receives the XHTML data in S30 of FIG. 2 and executes the printing process based on the received XHTML data.

  FIG. 8 shows a flowchart of the writing process. The server 50 reads the XHTML data received in S40 of FIG. 7 by a predetermined amount (S50). Next, the server 50 determines whether or not the end of the XHTML data has been read (S52). If YES here, the writing process ends. On the other hand, if NO in S52, the server 50 determines whether the XHTML data read in S50 includes the address of the image object (S54). If NO here, the process returns to S50 to read the next predetermined amount of XHTM data. On the other hand, if YES in S54, the process proceeds to S56.

  In S56, the server 50 downloads the image object. Specifically, the printer 10 transmits the image object file specified from the address to the device specified from the address of the image object file (for example, reference numeral 84 in FIG. 3 and reference numeral 106 in FIG. 5). To instruct. Thereby, the server 50 can acquire an image object. This image object is binary data.

  Next, the server 50 executes a resizing process on the image object (S58). The processing of S58 is executed only when resizing processing is necessary. When the resizing process is not necessary, the process of S58 is skipped. The server 50 reads absolute size information from the header information of the image object downloaded in S56. Further, the server 50 reads the print size information described in the XHTML data or the style sheet file received in S40. The server 50 determines whether or not resizing processing is necessary by comparing the print size information and the absolute size information. If the determination is affirmative, the server 50 resizes (for example, reduces) the image object so as to conform to the print size information. A known method may be used as the resizing method. Here, description of the resizing method is omitted. The image object after the resizing process is also binary data.

  Next, the server 50 executes a rotation process on the image object (S60). The process of S60 is executed only when the rotation process is necessary. When the rotation process is not necessary, the process of S60 is skipped. The server 50 reads the rotation angle information described in the XHTML data or the style sheet file received in S40. The server 50 determines whether the rotation process is necessary by determining whether the rotation angle information is zero. If a positive determination is made here, the server 50 rotates the image object so as to match the rotation angle information. A known method may be used as the rotation method. Here, the description of the rotation method is omitted. The image object after the rotation process is also binary data.

  As described above, the image object downloaded in S56 may or may not be executed in S58 and / or S60. Hereinafter, any image object is referred to as a “processed image object”. The server 50 writes the data corresponding to the processed image object in the XHTML data received in S40 (S62). FIG. 6 shows an example of XHTML data after the processing of S62 is executed. The XHTML data 110 in FIG. 6 is obtained by writing the processed image object in the XHTML data 100 in FIG. The XHTML data 110 includes data 116 corresponding to the image object. As described above, the processed image object is binary data. XHTML data is data described in a text format. The server 50 converts the processed image object from binary data to text data. For this conversion, a description method called a base 64 is used. The XHTML data 110 includes a character string 116 a that specifies the description method of the base 64. The server 50 creates text data corresponding to the processed image object (binary data) by converting the image object of binary data into text. FIG. 6 shows an example of text data 116 well. When S62 ends, the server 50 returns to S50 and reads the next predetermined amount of XHTML data.

  As described above, the processed XHTML data 110 is transmitted to the printer 10 or the like in S44 of FIG. The printer 10 or the like can reproduce the processed image object by analyzing the contents of the XHTML data 110. The printer 10 creates bitmap data by rasterizing the processed image object, and prints based on the bitmap data.

  The printer system 2 of the embodiment has been described in detail. In this printer system 2, the format of print data before processing (XHTML format) received by the printer 10 and transmitted to the server 50 matches the format of print data after processing created by the server 50. . For this reason, the printer 10 or the like can perform printing based on the processed print data. According to the printer system 2 described above, the printer 10 and the like can reliably print based on the processed print data created by the server 50.

  In addition, the printer 10 does not transmit XHTML data that does not include the address of the image object to the server 50. Further, even if the XHTML data includes the address of the image object, the printer 10 does not need to perform rotation processing and resizing processing, and if it is within the allowable range of the memory, the printer 10 sends the XHTML data to the server 50. Do not send. According to these configurations, the printer 10 can execute the printing process without sending the XHTML data to the server 50 and waiting for it to be returned. For this reason, the printing process can be executed at high speed.

  Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above. The modifications of the above embodiment are listed below.

(1) In the above embodiment, rotation processing and resizing processing are employed as examples of deformation processing for an image object. However, other deformation processing (gradation, painting, color change, blurring, shadow addition, up / down / left / right reversal, color / brightness reversal, etc.) for the image object may be employed. In this case, information instructing execution of these deformation processes may be included in the XHTML data or the style sheet file. The printer 10 may determine whether or not it is necessary to execute these transformation processes, and may transmit XHTML data to the server 50 if necessary.

(2) The download of the image object may be executed by the printer 10. In this case, the printer 10 transmits the XHTML data and the downloaded image object to the server 50. In this case, the server 50 does not need to download the image object.

(3) The printer 10 described above does not transmit print data other than the XHTML format to the server 50. However, the printer 10 may transmit print data other than the XHTML format to the server 50. In this case, the server 50 may return print data (processed print data) in the same format as that transmitted from the printer 10 to the printer 10.

(4) The process of S26 in FIG. 2 may be executed after S18 and before S20. In this case, if a positive determination is made in the process of S26, the process may proceed to S28. If a negative determination is made in the process of S26, the process may proceed to S20.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
