Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for outputting or transferring print data to a printer.
[0002]
[Prior art]
A page printer typified by a laser printer prints one page of print data or transferred data output from a host in a memory, and then prints in page units. For this reason, since print data for one page is temporarily stored on the printer side, the print data for one page can be rotated on the printer side in accordance with the orientation of the print paper. And the orientation of the text can be matched with the orientation of the printing paper.
[0003]
[Problems to be solved by the invention]
A page printer requires a large-capacity memory to construct print data for one page. In particular, if the resolution of a print image increases, the required memory capacity increases, and for example, a memory of several tens of megabytes or more is required. Since this large-capacity memory is equipped with a printer, the cost of the page printer tends to increase. For this reason, even with a page printer, a system that can print data sent from the host in order, such as an inkjet printer, reduces the memory capacity required for the printer and reduces the cost of the page printer. It will be a big merit if it can be lowered.
[0004]
However, if the data transmitted from the host is to be printed in order, it is necessary to transfer the print data from the host to the printer in accordance with the orientation of the paper set in the printer. In other words, the host recognizes the orientation of the paper installed in the printer, and if the orientation of the paper and the orientation of the print image are not the same, the print data is rotated in advance to change the orientation of the print image to the orientation of the paper. It is necessary to transfer to the printer after matching. If the image has a low resolution, the processing load on the host side may be small. However, if the image has a high resolution, the amount of data to be rotated is very large, which places a heavy burden on the host side. Therefore, the method of rotating the print data on the host side and then transferring it to the printer is not a preferable method when considering the burden on the host side. Also, with this method, the host side must recognize in advance the orientation of the paper set in the printer as a precondition for performing rotation processing, so information on the orientation of the paper is exchanged between the host and the printer. The function to do is essential.
[0005]
Therefore, in the present invention, printing is performed by aligning the orientation of the print image with the orientation of the paper on the printer side, without installing a large-capacity memory for recording the entire print data of one page. Further, it is an object of the present invention to provide a data transfer method and a data reception method that can greatly reduce the burden on the host during printing. It is also an object of the present invention to provide a low-cost printing apparatus capable of printing print data with a small memory capacity regardless of the orientation of paper by adopting this data transfer method and data reception method. It is.
[0006]
[Means for Solving the Problems]
In order to send n-dimensional transferred data in order in small units, a method of sending sliced in n-1 dimensions is usually adopted. Actually, instead of making it completely n-1 dimensional, the spread in the n-dimensional direction is limited to a predetermined range, and divided into n-1 dimensional units for transfer. For example, in the case of two-dimensional transfer data such as print data, the data is divided into one-dimensional, that is, line-shaped transfer data and transmitted, and the one-dimensional transfer data is printed in order at the receiving end. Restore the dimension transferred data. Further, if it is three-dimensional transferred data, it is divided and transmitted into two-dimensional planar transfer data, and the three-dimensional transferred data can be restored by arranging them in order at the receiving destination. Therefore, on the receiving side, the only way to restore the transferred data is to assemble the transferred data in the direction sliced on the transmitting side. For example, data transmitted by dividing two-dimensional transferred data of XY coordinates into line-shaped transfer data in the X direction must be reproduced in the X direction.
[0007]
On the other hand, when the two-dimensional transfer data is divided into one-dimensional transfer data having an L-shaped configuration in the X and Y directions and transmitted, the transfer data is transferred to the X and Y directions on the receiving side. It is possible to assemble in any direction. Also, in the case of three-dimensional data to be transferred, if the data is divided into two-dimensional transfer data having a configuration in which the surface in the X direction and the surface in the Y direction are combined like an L shape, It is possible to assemble in any of the Y and Y directions. Furthermore, the data is divided into two-dimensional transfer data that is transmitted by dividing the X-direction plane, the Y-direction plane, and the Z-direction (may be time axis) unit into a unit. Can be assembled in any of the X, Y and Z directions. Therefore, the receiving side can freely select the direction for assembling the transfer data.
[0008]
Therefore, in the present invention, when n-dimensional transfer data (n is an integer of 2 or more) is divided into n-1 dimensional transfer data and transferred, (1) the transfer data is 2 or more n In the following directions, divide into n-1 dimensional subunits in order from the origin, (2) combine subunits in the same order in each direction, and (3) exclude the origin side from the intersection of the subunits Transfer data. In this data transfer method, each direction of n-1 dimensional subunits divided in order from the origin in the direction of 2 or more and n or less from the transferred data of n dimensions (n is an integer of 2 or more), Of the plurality of subunits in the same order, transfer data according to the present invention including a portion excluding the origin side from a portion where the subunits intersect is generated and transferred in order. That is, the transfer data of the present invention is a combination of n-1 dimensional subunits in which the transferred data is divided in each direction, and includes the subunit portion included in the previously sent transfer data. It will not be.
[0009]
Therefore, when the transfer data is received in order, the sub-unit part in the predetermined direction included in the transfer data received in advance is added to the sub-unit part in the predetermined direction included in the received transfer data, The subunit in the predetermined direction of the transferred data can be reconfigured, and the predetermined direction for reconstructing the subunit can be arbitrarily set on the receiving side. The transfer data transfer side can transmit certain transfer data regardless of the direction in which the transfer data reception side assembles the subunit. For this reason, the transfer (outgoing) side and the receiving side can be developed and designed independently.
[0010]
Therefore, the data transfer method of the present invention includes a step of generating the transfer data of the present invention and a step of sequentially transferring the generated transfer data, and the data receiving method receives the transfer data in order. And a step of reconstructing the subunit from the transfer data as described above. A transmission / reception method in which the receiving side can independently select the direction in which the data is reconstructed by combining the process of generating and transferring the transfer data and the process of receiving the transfer data and reconfiguring the subunit. Can be provided.
[0011]
The data transfer method and the data reception method of the present invention are recorded on a suitable recording medium as a program or program product having instructions that allow a data processing apparatus such as a computer or a CPU to execute the processing of the above steps, or a network. Can be provided through. The data processing apparatus having means for receiving transfer data and means for reconfiguring subunits from transfer data according to the present invention is, for example, a printing apparatus if the transferred data is two-dimensional print data. The means for generating transfer data and the data processing apparatus for transmitting or transferring according to the present invention are a printer driver or a computer in which a printer driver is installed.
[0012]
That is, two-dimensional print data is divided into X-direction and Y-direction subunits (line data), and the same order of subunits in the X-direction and Y-direction is included in one transfer data. Of these subunits, the portion that is on the origin side from the portion where the subunits intersect, that is, the portion that is included in the transfer data generated before this transfer data is excluded from the current transfer data It becomes. Therefore, the transfer data includes all or a part of the subunits in the X direction and the Y direction. By combining with the part of the subunits included in the transfer data transferred before that, the X direction and the Y direction are combined. Subunits in any direction can be constructed. For this reason, with the printing apparatus according to the present invention, printing is performed in both the X direction and the Y direction by assembling the subunits included in the transfer data without receiving all the transfer data. be able to.
[0013]
In the case of two-dimensional data, the transfer data of the present invention includes two-direction subunits or portions thereof, so the remaining portion that was not immediately used for subunit reconstruction needs to be stored in a memory or the like. There is. Therefore, in order to reconstruct the transfer data, a certain amount of memory is required, but a memory that can store print data for one page is not necessary. In addition, since the subunit can be constructed in any direction, the rotation processing function is unnecessary.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings. 1 to 3 show an outline of transfer data according to the present invention. FIG. 1 shows an example in which the transferred data TD (2) is two-dimensional. Therefore, the transferred data TD (2) is divided in order from the origin O in the X direction and the Y direction. Thus, a plurality of one-dimensional (line-shaped) subunit data DX (sub-units in the X direction) divided in the X direction and a plurality of line-shaped subunit data DY (Y direction) divided in the Y direction. Are generated). Further, the subunits DX and DY are combined in the same order, such as first to second and second to second. When the third subunits DX and DY are combined in the same order, for example, the subunit closer to the origin O than the portion D0 where they intersect is included in the second subunit and the first subunit. Therefore, as the third data to be transferred in the X direction, the part BDX except the origin O side of the part D0 that intersects with the subunit DX and the part D0 that intersects may be transferred. Further, as the third data to be transferred in the Y direction, the part BDY excluding the origin O side of the part D0 that intersects with the subunit DY and the part D0 that intersects may be transferred.
[0015]
For this reason, the transfer data BD can be configured by the portion of the subunits DX and DY excluding the portion on the origin O side from the intersecting portion D0. That is, the transfer data BD of the present invention (1) divides the transferred data TD (2) into two-dimensional X and Y directions in order from the origin O into one-dimensional subunits DX and DY (2 (3) generated by combining the subunits DX and DY in the same order in each direction, and (3) excluding the origin O side from the portion D0 where the subunits DX and DY intersect. The algorithm for generating the transfer data BD is not necessarily the above, but the transfer data BD is a one-dimensional subunit DX obtained by dividing the transfer data TD (2) in order from the origin O in two directions. And DY, a portion of the plurality of subunits DX and DY in the same order in the same order, except for the portion D0 where the subunits intersect, excluding the origin O side, that is, data BDX, BDY and D0 It will be prepared.
[0016]
The transfer data BD of the present invention is visually L-shaped transfer data as shown in FIG. 1, and transfer data BD1, BD2,... BDi (i is an integer) are generated in order from the origin O side. In turn, the amount of data decreases. These transfer data BDi do not need to be sent in the L-shape, and data BDX, BDY and D0 are transferred in an appropriate order following a header including information specifying data such as the order.
[0017]
The side that has received the transfer data BDi includes the portions BDX and D0 of the subunit DX in the X direction and the portions BDY and D0 of the subunit DY in the Y direction in each transfer data BDi. Units can also be rebuilt. If the X-direction subunit DX is reconstructed by the third transfer data BD3, the predetermined direction included in the received transfer data BD3, that is, the portions BDX and D0 of the X-direction subunit DX are set in advance. By adding the partial ADX of the subunit DX included in the received transfer data BD2 and BD1, the third subunit DX in the X direction can be reconstructed. The subunit DY in the Y direction can be similarly reconstructed, and the reconstructing direction can be independently selected on the receiving side.
[0018]
The data transfer method and data receiving method of the present invention described based on the two-dimensional transferred data TD (2) in FIG. 1 can be applied to transferred data of three or more dimensions. However, n-dimensional transfer data of three or more dimensions can be transferred in the direction of 2 to n on the receiving side by transferring transfer data including subunits sliced in the direction of 2 to n (2 to n). This gives you the freedom to assemble the subunits. For example, in the example shown in FIG. 2, the three-dimensional transferred data TD (3) is decomposed into subunits in the X direction and the Y direction to form the transfer data BD. There is freedom. On the other hand, in the example shown in FIG. 3, the three-dimensional transferred data TD (3) is broken down into subunits in the X, Y, and Z directions to form transfer data BD. There is freedom in the Y and Z directions.
[0019]
In the example shown in FIG. 2, the transfer data BD is generated and transferred by dividing the three-dimensional transfer data TD (3) into the two-direction submodules DX and DY described with reference to FIG. Yes. Therefore, the transferred data is the same as that described above except that each submodule DX and DY is changed to two-dimensional (planar) data and the intersecting portion D0 is changed to one-dimensional (line) data. TD (3) can be divided and transferred to transfer data BD. Further, on the side receiving the transfer data BD, the submodule can be reconstructed in either the X direction or the Y direction.
[0020]
In the example shown in FIG. 3, the transfer data BD is generated by dividing the three-dimensional transferred data TD (3) into subunits in the X direction, the Y direction, and the Z direction. Accordingly, the transfer data BD includes a two-dimensional subunit DX decomposed in the X direction, a two-dimensional subunit DY decomposed in the Y direction, and a two-dimensional subunit DZ decomposed in the Z direction. , And the sub-units DX, DY and DZ in the same order, and further, a portion excluding the origin O side from a portion where these intersect (which is 0-dimensional data in this example) D0. . Accordingly, the side that has received the transfer data BD adds the sub-unit portion included in the transfer data BD received in advance, since the transfer data BD includes the sub-unit portion divided in each of the three-dimensional directions. By doing so, subunits can be reconstructed in any of the three dimensions.
[0021]
FIG. 4 shows an example in which the data transfer method and the reception method of the present invention are applied to transmission / reception of printing data. In this example, the printer driver 13 installed in the host computer 1 functions to generate and transfer the transfer data BD, and the CPU 28 of the printer 2 functions to reconstruct subunits in an arbitrary direction from the transfer data BD. .
[0022]
The host computer 1 of this example includes an operating system 11, an application 12 for processing text data and image data, and two-dimensional data in which a plurality of dots are collected from text data and image data, that is, raster data (2 And a printer driver (or driver program) 13 that disassembles the data into a plurality of transfer data BD and transfers the data to the printer 2. The transfer data BD output from the printer driver 13 is supplied to the printer 2 via an appropriate interface 14 such as RS232C or USB.
[0023]
The printer driver 13 has a function 15 for sequentially dividing the two-dimensional raster data TD (2) for printing from the origin O into subunits DX and DY in the X direction and the Y direction, and 1 divided in the X direction. A function 16 for combining the subunits DX and DY in the same order among the plurality of dimensional subunit data DX and the one-dimensional subunit data DY divided in the Y direction, and the combined sub A function 17 for generating transfer data BD by excluding data on the origin O side from a portion D0 where the units DX and DY intersect with each other and a function 18 for transferring the generated transfer data BD to the printer 2 are provided.
[0024]
The dividing function 15 divides the two-dimensional raster data TD (2), which is a set of a plurality of dots, into small blocks of 8 dots × 8 dots, and uses this small block as a unit for one-dimensional line data, that is, sub Unit data DX and DY are generated. If one dot is 1 bit, the small block data is 64 bits, that is, 8 bytes of data, and the data is easily arranged in a line. Therefore, the transfer data BD adds header information including the offset and data size of the intersection data D0, the offset and data size of the data BDX, the offset and data size of the data BDY, and the intersection data D0, data BDX, and data BDY are added. Lines can be arranged and output to the printer 2.
[0025]
The printer 2 generates subunits in the X direction or Y direction from the transfer data BD output from the host 1, and prints in units of the subunits. The printer 2 includes a print engine or printing mechanism 21, a paper detection unit 22 that detects the orientation of the paper 4 printed by the printing mechanism 21, and a control unit 23 that controls the entire printer 2. The control unit 23 sequentially generates subunits DX or DY in the direction corresponding to the orientation of the set paper 4 from the transfer data BD, and the print engine 21 prints image data and document data in an appropriate direction on the paper 4. The The control unit 23 includes an interface 24 that receives or acquires transfer data BDi, a CPU 28, a ROM 29 in which a printing program P 1 is recorded, a RAM 30, and a mechanical control unit 27 that controls the print engine 21. These are connected by a bus 33. The RAM 30 has an area 25 for temporarily storing the received transfer data BD, an area 26 for storing data that is not used immediately for printing in the transfer data BD, and data for managing the data recorded in the area 26. And a management table 32 in which is written.
[0026]
FIG. 5 shows a schematic function for printing from the transfer data BD on the printer 2 side. The CPU 28 uses the print program P1 in the ROM 29 to reconstruct the X-direction or Y-direction subunit data DX or DY from the transfer data BD, and the mechanical control section 27 stores the reconstructed subunit data DX or DY. And a function 36 for outputting to the print engine 21 via the. The reconstruction function 35 extracts the data BDX or BDY of the subunit in the printing direction immediately with the intersection data D0 from the transfer data BDi received in the buffer 25 according to the direction of the paper 4 set in the printer 2, and the buffer 26 is reconstructed by combining the data ADX or ADY of the X-direction or Y-direction subunit stored in advance in the line 26, and the remaining data BDY or BDX is stored in the buffer 26. save. Therefore, the reconstruction function 35 identifies the data D0, BDY, and BDX included in the transfer data BD based on the offset and data size of each data included in the header information added by the printer driver, and the remaining data When the data is recorded in the buffer 26, management data such as an address is written into the management table 32. Thereby, data ADY or ADX for reconstructing the subunit DX or DY can be generated from the data BDY or BDX recorded in the buffer 26.
[0027]
As shown in FIG. 6, a state in which subunit data DY in the Y direction is sequentially generated and printed in the Y direction is shown. When printing in the X direction, it is only necessary to generate the subunit data DX in the X direction in order, and the printer 2 of this example does not need to rotate the print data in accordance with the orientation of the paper 4.
[0028]
In step 81, the transfer data BD1 is first received. Since the first transfer data BD1 includes all data of the first subunits DX and DY, a subunit DY in the Y direction can be generated from the transfer data BD1 and printed in step 82. When the second transfer data BD2 is received at step 83, the second transfer data BD2 only includes a part of the second subunit DY, and the first transfer data received earlier. The second subunit DY is generated by combining the data ADY (a part of the data BDX) included in the BD 1 and is printed in step 84. Similarly, the third transfer data BD3 is received at step 85, the third subunit DY is generated and printed at step 86, the fourth transfer data BD4 is received at step 87, and the fourth transfer data BD4 is received at step 88. The subunit DY is printed. In step 89, the fifth transfer data BD5 is received, and in step 90, the fifth subunit DY is printed. In step 91, the last transfer data BD6 is received. In this example, since the number of divisions is the same in the X direction and the Y direction, the last transfer data BDL is only the intersection data D0. It can be said that the last transfer data BDL becomes the intersection data D0 when the subunit DX in the X direction coincides with the subunit DY in the Y direction. When the numbers of divisions in the X direction and Y direction are different, the last transfer data BDL is a component that generates the intersection data D0 and the subunit having the larger number of divisions.
[0029]
By receiving the six transfer data BD1 to BDL in this way, one page can be printed in the Y direction. Similarly, by receiving BD1 to BDL, subunits DX in the X direction can be generated in order, so that one page can be printed in the X direction. Therefore, the driver program 12 can output the transfer data BD regardless of the printing direction of the printer 2. Further, the printer 2 can print in any direction in both the X direction and the Y direction without being affected by the output of the printer driver 13. Therefore, a rotation process for printing in an arbitrary direction is not required, and neither a mechanism nor a memory for that purpose is required. Further, it is not necessary to download one page in advance, and the printer 2 of this example can print in any direction at high speed.
[0030]
FIG. 7 is a flowchart showing the processing of the driver program 12. In step 51, the division function 15 divides the two-dimensional raster data TD (2) into a plurality of subunit data DX and DY in the X direction and the Y direction. Next, in step 52, the data DX and DY in the same order are combined by the combination function 16, and in step 53, the portion that has been transferred by the previous transfer data by the generation function 17, that is, from the intersection data D0 to the origin side. Transfer data BD is generated excluding the portion. Of course, the transfer data BD may be combined by combining the data obtained by previously excluding the origin side portion from the intersection data D0, and the algorithm for generating the transfer data BD is not limited to this. When the transfer data BD is generated, in step 54, the transfer function 18 adds the header information H to the transfer data BD and outputs it to the printer 2. In step 55, the process is continued until all the data of the raster data TD (2) is output to the printer 2. A driver program or program product having instructions that can be executed by a computer can be provided by being recorded on a suitable recording medium such as a CD-ROM, or can be provided via a computer network.
[0031]
FIG. 8 shows a process executed by the CPU 28 by the program P1 of the printer 2 using a flow diagram. Of course, a process for reconfiguring the line data DX or DY from the transfer data BD by preparing a dedicated ASIC or the like instead of the CPU 28 can be performed by hardware or software. In step 61, the printing direction is set. When the transfer data BD is received in step 62, components in the printing direction are extracted from the transfer data BD by the reconstruction function 35 in step 63, and other components are temporarily stored in the buffer 26. In step 64, the unused component of the transfer data BD received in advance is added to the extracted component of the transfer data BD to reconstruct print data (subunit data) for one line. In step 65, the data is output to the print engine 21 by the transfer function 36. Thereby, printing is performed. At this time, depending on the printing method or printing direction, processing such as switching the line and column of the print data for one line reconstructed in the buffer or memory is performed, and the nozzle arrangement direction of the head for inkjet printing and the thermal Print data is output to the print engine in accordance with the arrangement direction of the heating resistors of the head. The print data may be output to the print engine in accordance with the laser scanning direction of the laser printer.
[0032]
By performing the processing from step 62 until the transfer data BD ends in step 66, printing for one page can be performed from an arbitrary direction. The firmware P1 of the printer 2 capable of such processing can be provided by being recorded in a ROM as a program having instructions capable of executing the above steps. It can also be provided via a computer network.
[0033]
As described above, the printer 2 of this example can perform sequential printing in an arbitrary direction using the transfer data received sequentially. Therefore, printing can be performed in any direction set on the printer side without a rotation processing function or a page memory. A memory for storing a part of the transfer data for later printing is necessary, but the capacity is about 1/4 page. Therefore, according to the present invention, not only a page printer but also a sequential printer such as an ink jet printer can be printed in an arbitrary direction only by installing a small-capacity memory, and an easy-to-use printer can be provided. In particular, when trying to store a high-quality color image for one page, an enormous amount of memory is required. However, according to the present invention, since it can be output sequentially in any direction, the economic effect is great. In addition, since the time accumulated in the memory can be saved, the time for starting printing can be shortened. In addition, high-speed printing is possible with a small-capacity memory.
[0034]
In addition, the data transfer method and data reception method of the present invention are not limited to two-dimensional transferred data, as described at the beginning, but three-dimensional or higher-dimensional transferred data such as stereoscopic video and video data. The present invention is also applicable when transferring data.
[0035]
【The invention's effect】
As described above, in the present invention, when n-dimensional transferred data is restored on the receiving side, the direction can be freely selected. Therefore, when sending data for which the reproduction direction is questioned, the transmission source and the reception destination can be made independent regardless of the reproduction direction. That is, the transmitting side can always transfer data in a fixed format, and the receiving side can select an arbitrary reproduction direction.
