Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printer host suitable for double-sided printing and a storage medium storing an operation program thereof.
[0002]
[Prior art]
Conventionally, as an ink jet printer capable of duplex printing, for example, there is one described in Japanese Patent Laid-Open No. 5-147208. When the host of this inkjet printer is instructed to perform double-sided printing, it creates print commands for odd pages and even pages, and creates print commands in page order so that the images of odd and even pages are flipped upside down. This is sent to the printer.
[0003]
By the way, in reality, there are practically no commercially available inkjet printers capable of duplex printing. In this way, when performing duplex printing with an inkjet printer that does not have a duplex printing function, the user first designates printing of odd-numbered pages and executes this, and then only the odd-numbered pages are printed. After the paper is turned over and set in the printer, printing of even-numbered pages is designated, and even-numbered pages are printed on the back of the paper. That is, a host of an inkjet printer that does not have a duplex printing function first transmits only odd-numbered page print commands to the printer, and then transmits only even-numbered page print commands to the printer.
[0004]
[Problems to be solved by the invention]
In the prior art, if a printer that does not have a duplex printing function is connected to a printer host for a printer capable of duplex printing, if the printer host issues a duplex printing instruction, the top and bottom are reversed for each page. There is a problem that it is printed.
[0005]
Conversely, when an inkjet printer having a duplex printing function is connected to a printer host for a printer that does not have a duplex printing function, the printer itself has a duplex printing function, but the host side Since the user cannot instruct both sides printing, the user has to instruct the host to print odd pages and then instruct to print even pages, which is very inconvenient.

[0041]
Next, the operation of the printer system of this embodiment will be described with reference to the flowchart shown in FIG.
[0042]
The host 10 receives various printing conditions by the operation of the user input unit 72 (step 1). Printing conditions include paper size, paper type, margin area in printing paper, single-sided printing / double-sided printing, and the like. When the duplex printing mode designation is accepted, a confirmation message “Is duplex ink set?” Is displayed on the display screen. Further, as shown in FIG. 6, odd-numbered sheets 91 a and even-numbered sheets 91 b are displayed on the screen of the display unit 71. On the displayed sheet 91a, the vertical dimension 92 and the horizontal dimension 93 of the sheet are also displayed. Further, the dimension input areas 94a, 94b, 94c, and 94d of the upper margin area, the lower margin area, the left margin area, and the right margin area are displayed at the upper, lower, left, and right positions, respectively.
[0043]
The user designates a margin area in the printing paper while viewing this screen. First, the user specifies whether to specify the margin area for even pages or the margin area for odd pages. This is because during double-sided printing, the position of the binding margin is different between the odd and even pages, and the left and right margin areas of the odd pages are different from the left and right margin areas of the even pages. Subsequently, the user inputs dimensions in the dimension input areas 94a, 94b, 94c, and 94d of the upper margin area, the lower margin area, the left margin area, and the right margin area. For example, when the user designates the margin area specification of the even page and then inputs the size of each margin area, the margin area boundary line 95b is displayed in the paper 91b of the even page displayed. Further, in accordance with the setting of the margin area of the even-numbered page 91b, the margin area of the odd-numbered page is automatically set by the user interface control unit 73, and the border line 95a of the margin area is displayed in the displayed odd-numbered sheet 91a. The In the odd page margin setting, the top, bottom, right, and left margin dimensions of even pages are automatically set to the odd, top, bottom, left, and right margin dimensions, respectively. Is done. That is, the left margin dimension of even pages is automatically set to the right margin dimension of odd pages, and the right margin dimension of even pages is automatically set to the left margin dimension of odd pages. When the user wants to change the automatically set margin size of the odd page, the user further specifies the margin region of the odd page and inputs each margin region size. This input result has priority over the automatically set margin size.
[0044]
Subsequently, the host 10 accepts print execution by the operation of the user input unit 72 (step 2). The host 10 determines whether or not the double-sided printing mode is designated for this printing. If the double-sided printing mode is not designated, the host 10 creates a normal printing command for the single-sided printing mode, that is, a normal printing command (step 4). 30 (step 5). If the double-sided printing mode is designated, the transmission / reception unit 76 inquires of the printer 30 whether “double-sided printing is possible” (step 6).
[0045]
In response to this inquiry, if the attachment sensor 49 detects that the reversing mechanism 50 is attached, the printer 30 sends a response “duplex printing is possible” from the transmission / reception unit 82 to the host 10.
[0046]
If there is a response “printing on both sides” from the printer 30 (step 7), the inversion time setting unit 74 sets the inversion time of the paper in the duplex printing in the printer 30. This inversion time is transmitted from the transmission / reception unit 76 to the printer 30. When performing double-sided printing with the inkjet printer 30, after printing on the front surface, if the front and back surfaces of the paper are reversed before the ink on the front surface dries, the ink on the front surface rubs against the rollers and the surface print quality deteriorates. Resulting in. For this reason, in this embodiment, the inversion time setting unit 74 sets the inversion time according to the paper type set in the printing condition setting (step 1). The printing condition storage unit 63 stores in advance the relationship between the paper type and the inversion time, and the inversion time setting unit 63 determines the inversion time with reference to this relationship. Here, the inversion time is determined according to only the paper type, but the inversion time may be determined according to the paper type and the ink type. The inversion time may be set by user input.
[0047]
When the paper inversion time is set (step 8), a print command for the duplex printing mode is created (step 8), and this is transmitted from the transmission / reception unit 76 to the printer 30 (step 9).
[0048]
When duplex printing is performed by the printer 30, as shown in FIG. 7A, after the odd page 1a is printed and then the paper 1 is reversed by the reversing mechanism 50 of the printer 30, as shown in FIG. 7B. Since the upper and lower sides of the paper 1 are reversed, when printing the back surface of the paper 1, that is, the even page 1b, it is necessary to rotate the image by 180 °. In the same figure, the arrows indicate the paper supply direction to the print head, the upper, lower, left and right with () in FIG. 4B indicate the upper, lower, left and right of the odd page 1a on the back, and the up, down, left and right without () The top, bottom, left and right of the even page 1b of the table are shown. Therefore, in the creation of the print command for the duplex printing mode (step 9), the print command is created by rotating the image of the even page 1b by 180 ° with respect to the image of the odd page 1a.
[0049]
Specifically, first, the rasterizer 65 of the print command creation unit 64 converts the drawing command stored in the spool file storage unit 62 into RGB image data, which is developed in the development area 66. Next, the color conversion / halftone processing unit 67 performs color conversion processing, halftone processing, and the like on the RGB image data to convert it into CMYK binarized image data, which is developed in a development area 68. Then, after the command conversion unit 69 converts the print command into a print command that can be interpreted by the printer 30, the print command is transmitted from the transmission / reception unit 76 to the printer 30. When a print command for one page is transmitted to the printer 30, the print command creation unit 64 creates a print command for the next page, that is, the back side. At this time, the rasterizer 65 converts the drawing command into RGB image data according to an instruction from the rasterization control unit 70, and develops the image in the development area 66 with the image upside down. Next, when the color conversion / halftone processing unit 67 reads the RGB image data from the development area 66, the color conversion / halftone processing unit 67 reads the RGB image data from the opposite direction to the normal direction, converts this to CMYK binary image data, Expand in the expansion area 68. As a result, the back side image data is developed in the development area 68 in a state rotated by 180 °. The CMYK binarized image data is converted into a command by the commanding unit 69 and transmitted to the printer 30 as a print command for the back side.
[0050]
When the printer 30 receives the above print command, it prints on the surface of the paper based on the odd page print command sent earlier. When printing on the front side is completed, the sheet is sent to the reversing mechanism 50, where the front and back sides are reversed and sent again to the position facing the print head. Then, printing based on the print command of the even page sent later is performed on this back surface, and printing is performed on both the front and back surfaces. At this time, the reversal time from when the front surface is printed to when printing of the back surface is started is the reversal time sent from the host 10 in step 8. As described above, in this embodiment, printing on the back surface is not performed until the ink on the front surface is dried, so that it is possible to prevent the surface from rubbing against a roller or the like to deteriorate print quality.
[0051]
In step 7, if there is no response “printing on both sides” from the printer 30, the print command creation unit 64 sequentially creates only odd page print commands (step 11), and the transmission / reception unit 76 transmits this to the printer 30. (Step 12). In creating a print command for only odd pages, the rasterization control unit 70 of the print command creation unit 64 gives an instruction to the rasterizer 65 and sends a drawing command for only odd pages from the spool file storage unit 62 to the rasterizer 65. Read it. The printer 30 performs printing in the normal single-sided printing mode based on the print command for only odd pages.
[0052]
When the transmission of the print command for only odd pages is completed (step 12), the transmission / reception unit 76 inquires of the printer 30 whether printing of odd pages has been completed (step 13). In response to this inquiry, when “odd page printing end” is received from the printer 30 (step 14), the display unit 71 of the host 10 sends a message “Odd page printing has been completed. Please "and an" OK "button are also displayed (step 15).
[0053]
The user sees this display and turns over the paper 1 on which only odd pages are printed on the paper discharge tray 48 (shown in FIG. 2) of the printer 30 and sets it on the paper feed tray 44. When the setting is completed, an “OK” button displayed on the display unit 71 is clicked.
[0054]
When the “OK” button is clicked, the host 10 creates a print command for only even pages (step 17), and sequentially transmits this to the printer 30 (step 18). Upon receiving this print command, the printer 30 prints even pages on the back side of the paper on which odd pages are printed.
[0055]
As described above, in this embodiment, even when an inkjet printer having a duplex printing function is connected to the host 10 or an inkjet printer not having a duplex printing function is connected, duplex printing is performed. If indicated, double-sided printing can be performed, and the burden on the user can be reduced.
[0056]
Moreover, even if duplex printing is performed with an inkjet printer having a duplex printing function, the paper is not reversed until the ink on the first printed side is dry, thus preventing deterioration in print quality on the first printed side. it can.
[0057]
Furthermore, in the present embodiment, the left and right margin areas that are different between the odd-numbered pages and the even-numbered pages can be set in consideration of the binding margin of the paper during double-sided printing. This margin area can also be set in the single-sided printing mode.
[0058]
When the application 61 sets the print area 2 as shown in FIG. 8A and sets the printing conditions (step 1), the margin area 95 as shown in FIG. 8B is set. The area that can be actually printed becomes the area inside the margin area, which is narrower than the initially planned area 2. For this reason, in this embodiment, when the blank area 95 overlaps a part of the print area 2 set by the application 61, as shown in FIGS. Thus, the image is developed in a reduced size without changing the aspect ratio so that the image of the entire page fits in the region 97 excluding the overlapping portion 96. As described above, when the image is reduced and developed, the image is not printed with the image size planned by the user, so that the image may be reduced or displayed to be reduced. Here, the image of the entire page is accommodated in the area 97 excluding the overlapping portion 96 in the print area 2, but the image in the initially set print area is accommodated in the area 97. You may do it. In this reduction operation, the rasterization control unit 70 determines the reduction ratio with reference to the print area and the blank area stored in the print condition storage unit 63, and when the rasterizer 65 expands the drawing command, the rasterizer 65 The reduction ratio is informed and the image is developed at the reduction ratio.
[0059]
In the above embodiment, the left and right binding margins of the printing paper are considered, but both directions of the left and right binding margins and the upper and lower binding margins may be considered.
[0060]
In this case, in the margin setting screen shown in FIG. 6, as shown in FIG. 9, a binding margin position designation area for selecting whether the binding margin position is the left or right or top and bottom of the sheet is displayed. Enable to specify left / right or top / bottom. In addition, if the binding margin position is on the left and right sides of the paper, as in the above embodiment, if the printer can perform double-sided printing, the printer host transmits a normal rotation print image print command for odd pages and even pages. With respect to, a print command of a reverse print image (an image obtained by rotating a normal print image by 180 °) is transmitted, and when the printer cannot perform double-sided printing, a print command for a normal print image is transmitted for both odd and even pages. If the binding margin position is above and below the paper, the printer host sends a print command for a normal print image for both odd-numbered pages and even-numbered pages when the printer can print on both sides, and odd-numbered pages when the printer cannot print on both sides. A normal print image print command is transmitted with respect to, and a reverse print image print command is transmitted with respect to even pages.
[0061]
【The invention's effect】
According to the present invention, even when an inkjet printer having a double-sided printing function is connected to the printer host or when an inkjet printer having no double-sided printing function is connected, if double-sided printing is instructed, Double-sided printing can be performed, and the burden on the user can be reduced.
