Abstract

PURPOSE:To conduct single-side printing and double-side printing automatically without changing printing data and the direction of the setting of cut paper by setting the direction of printing so that the binding margins of single-side printing and double-side printing are equalized on the basis of binding-margin positional information from a printer in a host system. CONSTITUTION:A printing control section 14 informs a host system 20 of binding-margin positional information indicating the presence of the positions of binding margins and binding holes together with printer information such as other form size, etc. The printing-direction control means 21 of the hots system 20 discriminates the presence of binding holes in cut paper 12 by binding- margin positional information notified from a printer 10. When the direction of printing at the time of surface printing and reverse printing in double-side printing and the direction of printing at the time of single-side printing are assigned by the printing-direction control means 21, the host system 20 informs the printer 10 of these printing-direction specified values. Consequently, the printer 10 conducts surface printing and reverse printing in single-side printing and double-side printing respectively according to the direction of printing assigned by the host system 20.

Description

[Detailed Description of the Invention] [Summary] Regarding the single-sided and double-sided printing control method of a printing device equipped with the function of printing on one-sided and double-sided sheets on cut paper, the printing device side prints according to the printing method and the presence or absence of binding holes. The aim is to make the binding margin position the same for single-sided printing and double-sided printing without changing the setting direction of data or cut paper. In contrast, in single-sided and double-sided printing control systems where print data is sent from a host system and the cut sheets with or without binding holes are printed in a predetermined binding direction and printing direction, the printing device side binds each cut sheet. Set it in the hopper with the substitute position above or below the paper feeding direction, and respond to printer information requests from the host system.
The printing device notifies the binding margin position information indicating the binding margin position of the cut paper and the presence or absence of binding holes, and the host system uses the pre-specified printing method, printing direction, binding direction, and binding margin position information. The printing direction is set so that the binding margin positions for double-sided printing and single-sided printing are the same, and the printing is sent to the printing device.

[Industrial application field]

The present invention sends print data from a host system to a printing device equipped with the function of printing on one and both sides of cut paper, and prints each cut paper with or without binding holes in a predetermined binding direction and printing direction. The present invention relates to single-sided and double-sided printing control methods when

[Conventional technology]

Even among printing devices that perform printing under the control of a host system, those equipped with a paper reversing mechanism are capable of both single-sided and double-sided printing. FIG. 8 shows the principle of a paper reversing mechanism for cut sheets used in a printing device having one-sided and two-sided printing functions.

In FIG. 8, 31 is cut paper cut into a standard size. Reference numeral 33 represents a paper reversing mechanism for reversing the cut sheets 31, 34 represents a printing unit that prints the cut sheets 31, and 35 represents a stacker on which the printed cut sheets 31 are stacked.

FIG. 9 shows a print control method (A) when performing double-sided printing ((A) in the same figure) and single-sided printing ((B) in the same figure) using the paper reversing mechanism 33 in FIG. 32 indicates the binding margin, and 33 indicates the binding hole provided in the binding margin 32.The binding margin 32 may or may not have the binding hole 33.

Double-sided printing and single-sided printing are performed using the paper reversing mechanism 33 in the following procedure.

(A) Double-sided printing (a) When performing double-sided printing, the cut paper 31 is fed from a hopper (not shown) to the position (■) of the paper reversing mechanism 33. (See FIG. 8(a) and FIG. 9(A)(a)) The paper feed direction is short edge feed (A4, B5, LT size) as shown in FIG. 9(A)(a). ), and the binding direction is left binding when viewed from the front side printing side, but the binding margin 32 (binding hole 3) of the cut paper 31 set in the hopper is
3) is on the right side. Further, the upper side of the cut paper 31 is indicated by U, and the lower side is indicated by L.

(b) The print section 34 first prints back side data on the lower side of the cut paper 31. (See Figures 6(c) and 9(A))) (c) The cut paper 31 printed on the back side is rotated as shown in Figure 8(c) to perform paper reversal.
), proceed in the directions of ■ and ■.

(a) The cut paper 31 that has advanced in the direction of ■ is switched back by a switch pack mechanism (not shown), and further advances from the direction of ■ in the direction of ■, as shown in FIG. 8(d).
It is reversed and goes to the printing section 34.

By inverting the cut paper 31, the upper side U becomes the lower side, the lower side becomes the upper side, and the binding margin 32 moves to the left side.

(e) The print section 34 prints front side data on the front surface U of the cut paper 31. (See FIG. 8(e) and FIG. 9(A)(c)) (f) The cut paper 31 printed on both sides is then discharged in the direction of are stacked with the left side. (Figure 8(f), Figure 9(A)
) (d)).

(B) Single-sided printing Next, in the case of single-sided printing, the paper feeding direction is short edge feeding as in the case of double-sided printing, the binding direction is left binding when viewed from the front side printing side, and the hopper has a binding margin of 32 (binding margin). Assume that it is set with hole 33) on the right side. Single-sided printing is performed in the following steps.

(a) A cut sheet 31 is fed from a hopper (not shown) to the position (■) of the sheet reversing mechanism 33. (Figure 8(a)
, see (a) in Figure 9(A)) (b) Cut paper 31
The front side data is printed on the lower side in the printing section 34. (See Figure 8 (0)), (e) in Figure 9 (B)) (c) Cuff with front side data printed) If the paper 31 is printed on one side, immediately turn it over without reversing the paper. The sheets advance in the direction and are ejected, and are stacked on the stacker 35 with the binding margin 32 on the left side. (See FIG. 8(f) and FIG. 9(B) (f)).

In this way, when double-sided printing and single-sided printing are performed using the same paper feeding direction, the binding margin positions for both sheets after printing are not the same, but are separated to the left and right as shown in the figure. However, if the printing positions are not the same for double-sided printing and single-sided printing, it is inconvenient because the load of post-processing such as binding processing performed after step 7 increases.

Therefore, in order to make the binding margin positions the same after double-sided printing and single-sided printing, a single-sided and double-sided printing control system (B) as shown in FIG. 10 is adopted for cut paper with binding holes.

FIG. 10(A) shows a double-sided printing control method, and its contents are the same as the double-sided printing control method shown in FIG. 9(A). The cut paper 31 printed on both sides is shown in FIG. 10(A).
As shown in (d), the binding 32 (I) is placed on the stacker 35.
They are stacked with the hole 33) on the left side.

Next, when performing single-sided printing, instead of instructing single-sided printing as shown in FIG. 10(B), a skip instruction to front-side printing is given during double-sided printing.

As a result, the back side printing becomes blank as shown in (e) of Figure 1O (B), and only the front (U) side of the reversed cut paper 31 is printed as shown in (f) of Figure 9 (B). Surface printing is performed as shown in .

Therefore, similarly to the case of double-sided printing shown in FIG. 10(A), the sheets are stacked on the stacker 35 with the binding 32 (stitch hole 33) on the left side. (See (darkening) in FIG. 10(B)) Next, in the case of the cut paper 31 without binding holes 33 in the binding 32, a single-sided and double-sided printing control system as shown in FIG. 11 is adopted.

FIG. 11(A) shows a double-sided printing control system, and its contents are the same as the double-sided printing control system shown in FIG. 10(A). The cut paper 31 printed on both sides is shown in FIG. 11 (A
), the sheets are stacked on the stacker 35 with the binding 32 on the left side.

In the case of single-sided printing, if the binding 32 is placed in the hopper with the binding 32 on the right side, as in the case of double-sided printing, the image shown in FIG.
As shown in e) and (f), single-sided printing is performed, and after printing, the binding 32 is stacked on the right side, so the binding margin position is reversed from when printing on both sides.

Therefore, when performing single-sided printing, a plurality of hoppers are provided, and as shown in (8) of FIG. 11(c), the hoppers (
(not shown).

The printing direction of the front side data during single-sided printing is changed so that the printing direction of the front side data during single-sided printing becomes the printing direction during front-side printing during double-sided printing shown in FIG. (See (h) in FIG. 11(c)).

As a result, the binding margin positions for single-sided printing and double-sided printing are the same, and the sheets are stacked on the stacker 35. (11th
(See (i) in Figure (c)) If the paper feed direction is A3. Even in the case of long-edge feeding such as A5 and B4 sizes, if you want to make the binding margin position the same after double-sided printing and single-sided printing, the setting direction of the cut paper 31 in the hopper and the single-sided printing on the printing device side An operation and process for changing the printing direction of the print data at the time is performed. Furthermore, when the binding margin position changes horizontally or vertically, the printing apparatus similarly performs operations and processes to change the setting direction of the cut sheet 31 in the hopper and the printing direction of print data during single-sided printing.

[Problem to be solved by the invention]

In a printing device equipped with one-sided and two-sided printing functions, when the binding margin position is the same for both duplex printing and after one-sided printing, the conventional one-sided and duplex printing control method determines whether the printing method is one-sided printing or two-sided printing. Furthermore, even if the printing method is the same, it is necessary to change the printing control method depending on the presence or absence of binding holes in the binding margin of the cut paper.

It is necessary to perform operations and processes on the printing device side to change the setting direction of the cut paper in the hopper and the printing direction of the print data when printing on one side, in accordance with the paper feeding direction of the cut paper and the binding margin position.

For this reason, there is an inconvenience in that it is necessary to always be aware of the printing method (single-sided or double-sided printing) and the presence or absence of binding holes, and to change the print control method for single-sided and double-sided printing accordingly. In particular, in order to deal with cases where there are binding holes in the binding margin, it is necessary to prepare multiple hoppers on the printing device side, and set cut sheets in the hoppers in accordance with the paper feed direction and binding margin position. There is an inconvenience in that complicated operations and processing are required to change the printing direction and the printing direction of print data during single-sided printing.

The present invention eliminates the need to change the print control method on the printing device side in response to the single-sided or double-sided printing method and the presence or absence of binding holes in the binding margin, and in both cases, the binding margin during single-sided printing and double-sided printing. It is an object of the present invention to provide a printing control method that is improved so that the hoppers can be made the same and does not require a plurality of hoppers in principle.

[Means to solve the problem]

First, the principle of the present invention will be explained separately for cases where the binding margin has binding holes and cases where there are no binding holes, that is, cases of cut paper with binding holes and cut paper without binding holes.

(A) Case of cut paper with binding holes The single-sided and double-sided printing control system of the present invention in the case of cut paper with binding holes will be explained with reference to FIG.

FIG. 2(A) explains the printing direction for printing paper (cut paper). As shown in (a) and (b) of the same figure, the printing direction in the case of cut paper used in portrait orientation is called boat rate. As shown in Figure (a), the boat rate is a boat rate 1 (hereinafter referred to as boat 1) that prints from left to right and from top to bottom, with the top left as the print start point and the bottom right as the print end point. ) and boat rate 2, which prints from right to left and from bottom to top, with the bottom right as the print start point and the top left as the print end point, as shown in (b) of the same figure.
(hereinafter referred to as boat 2).

On the other hand, as shown in FIGS. 3(c) and 4(d), the printing direction in the case of cut paper used in landscape orientation is called landscape. The landscape is further divided into Landscape 1 (hereinafter referred to as Land 1), which prints from left to right and from top to bottom, with the top left as the printing start point and the bottom right as the printing end point, as shown in FIG. , as shown in Figure (d), the printing start point is at the bottom right, the printing end point is at the top left, and the printing is divided into Landscape 2 (hereinafter referred to as Land 2), which prints from right to left and from bottom to top. .

Note that even if the cut paper is placed in a vertically long or horizontally long position, if the printing direction maintains the directional relationships of (a) to (d) above, the printing direction will be the boat 1, boat 2, boat 2, etc. They are called Land I and Land 2.

Figure 2 (B) shows double-sided printing ((a) to (d)) and single-sided printing ((a), (e), (f )). In this case, for double-sided printing and single-sided printing, first
Since double-sided printing and single-sided printing are performed in the same manner as described in FIGS. (A) and (B), detailed explanations of these print control operations will be omitted.

As you can see from the figure, when the binding hole position is on the upper side, that is, when the binding margin position matches the paper feeding direction,
Even if the cut paper is reversed, the binding margin position does not change. Therefore, by performing front-side printing in single-sided printing in the same printing direction as the front-side printing in double-sided printing, the same printing result including the binding hole position (binding direction) can be obtained. The binding hole positions (binding direction) of the cut sheets are the same. ((d) in Figure 2(B) and (
(See f)) This also applies to the case where the sheet feeding direction shown in FIG. 2(c) is long-side feeding. Since double-sided printing and single-sided printing in this case are performed in the same manner as the double-sided printing and single-sided printing explained earlier in FIGS. 9(A) and (B), detailed explanations of these print control operations will be omitted. do.

As you can see from the figure, even if the paper feed direction is long edge feed, if the binding hole position is on the top side and the binding margin position matches the paper feeding direction, the binding margin position will not change even if the cut paper is reversed. . Therefore, by performing front side printing in single-sided printing in the same printing direction as the front side printing in double-sided printing, the same printing result including the binding hole position (binding direction) can be obtained, and the same printing result as in double-sided printing and single-sided printing The binding hole positions (binding direction) of the cut paper at the time are the same. (Figure 2(c)
(See (j) and (2) of )) Above, we have explained the case where the binding margin position is on the upper side with respect to the paper feeding direction, but when the binding margin position is on the upper side with respect to the paper feeding direction, the same applies to double-sided printing. The binding hole positions (binding direction) of the cut paper can be made the same during single-sided printing.

By the way, when printing on cut paper, in order to realize the printing method (single-sided or double-sided), printing direction (bort rate or landscape), and binding direction (left/right or top/bottom) specified by the user to the host system. Furthermore, on the printing device side, it is necessary to appropriately change the printing direction in accordance with the sheet feeding direction of the cut sheet (short edge feeding or long edge feeding) and the setting position of the binding margin. In this case, as mentioned above, if you set the binding margin position to be on the upper (or lower) side with respect to the paper feeding direction, the binding hole position (binding direction) of the cut paper will be Since they are the same, desired printing can be achieved simply by changing the printing direction on the printing device side.

Figure 3 shows the printing direction specified to the printing device during double-sided printing and single-sided printing when the printing device is set so that the binding margin position is on the upper side with respect to the paper feeding direction, regardless of the paper feeding direction. are summarized in table format.

In other words, in the case of double-sided printing, the print direction shown in FIG.
Each printing direction for front side printing and back side printing shown in is specified to the printing device.

On the other hand, in the case of single-sided printing, the print direction (see Figure 1) corresponds to the printing direction and binding direction specified by the user to the host system, regardless of the paper size and paper feeding direction on the printing device side.
The printing direction during front side printing shown in B) is designated to the printing device.

This allows you to obtain the same printing results, including the binding direction.
The binding margin for double-sided printing and single-sided printing is the same.

(B) Case of cut paper without binding holes Next, the single-sided and double-sided printing control system of the present invention in the case of cut paper without binding holes will be explained with reference to FIG.

Since there is no distinction between the front and back sides of cut paper, in the case of cut paper without binding holes, even if you print data on the front (or back) side of the cut paper in the specified printing direction on the reversed cut paper, Even if data on the front side (N side) is printed in the same printing direction, the same printing result can be obtained.

Therefore, even if the binding margin position is specified for the cant paper, if there are no binding holes in the binding margin (in the case of blank paper), the reversed cut paper and the unreversed cut paper should be printed in the same printing direction on the front (back) side. Even if you print side data, you can obtain the same print result including the binding margin position. Next, this point will be explained with reference to FIG.

Figures 4 (A) and (B) explain the single-sided and double-sided printing methods using the short edge and free feed for the same print image on cut paper without binding holes. The figure (B) shows the case of single-sided printing.

In the case of double-sided printing, the print image and print direction on the upper system (host) side specified by the user are as shown in (a) to (c) of Figure 4(A), with the binding direction being left binding. Suppose the direction is boat 1. If the paper feeding direction of the printing device is short edge feeding, the printing device uses the same direction (
Both the same boat 1 as shown in (d) and (e) of A)
Front side printing and back side printing are performed. As a result, a predetermined left binding direction is obtained.

On the other hand, if the paper feeding direction of the printing device is long edge feeding, the printing device uses the same left binding direction.
As shown in (f) and (O) of the same figure (A), when printing on the front side, printing is performed on boat 1, which is the same as the upper system as the printing direction, and when printing on the back side, printing is performed on boat 2, which is opposite to the upper system. Printing is done in .

Next, in the case of one-sided printing, as in the case of back-side printing, see Figure 4 (
As shown in (a) to (c) of B), it is assumed that the binding direction is left binding and the printing direction is boat 1 or boat 2. If the paper feeding direction of the printing device is short edge feeding, the printing device uses the same left binding direction, so (B) in CB) in the same figure is used.
As shown in (e), when the host system is boat 1, printing is performed using the same printing direction boat 1, and when the host system is boat 2, printing is performed using the same boat 2 as the host system.

On the other hand, if the paper feeding direction of the printing device is long edge feeding, the printing device uses the same left binding direction.
As shown in (f) and (8) of the same figure (B), when the upper system is boat 1, printing is performed on the opposite printing direction boat 2, and when the upper system is boat 2, printing is performed on the opposite printing direction boat l. Printing is done in .

From the examples in FIGS. 4(A) and 4(B), it can be seen that the paper feeding direction of the printing device during single-sided printing is short edge feeding (for example, A4.B
5 and LT size), it can be seen that if single-sided printing is performed in the same printing direction as the printing direction during front-side printing in double-sided printing, the same printing result including the binding margin position can be obtained.

On the other hand, if the paper feeding direction of the printing device during single-sided printing is long edge feeding (for example, for A5 or B4 size),
In double-sided printing, the printing direction is reversed from the printing direction when printing on the front side (for example, when printing on boat 1 (2), printing direction on boat 2 (1
), land 1 (2) is changed to land 2 (1)), it can be seen that the same printing result including the binding margin position can be obtained.

FIG. 5 summarizes the above results in a table format.

In other words, if the printing direction of the printing device during single-sided printing is short edge feed, regardless of whether the printing direction is boat rate or landscape, or whether the binding direction is left/right or top/bottom, double-sided printing will not work. By performing single-sided printing in the same printing direction as the front-side printing, the same printing results including the binding direction can be obtained, and the binding margins for double-sided printing and single-sided printing are the same.

On the other hand, if the printing direction of the printing device during single-sided printing is long edge feed, regardless of whether the printing direction is boat rate or landscape, and whether the binding direction is left/right or top/bottom, By performing front side printing in single-sided printing in the printing direction opposite to the printing direction during front-side printing in double-sided printing, the same printing result including the binding direction can be obtained, and the binding margins for double-sided printing and single-sided printing are the same.

(c) Principle of the present invention From what was explained in sections (A) and (B) above, in the case of cut paper with binding holes, the binding margin position (stitching hole position) is at the top (
If the printing device notifies the upper system of the binding position of the cut paper set in the hopper, the upper system will know that it is printing on cut paper with binding holes. The printing direction can be recognized and designated to the printing device by referring to the printing direction setting table shown in FIG.

On the other hand, in the case of cut paper without binding holes, if the printer notifies the upper system of the paper feeding direction of the cut paper set in the hopper, the upper system refers to the printing direction setting table in Figure 5 and You can specify the printing direction.

However, as in the case of cut sheets with binding holes, if the paper is set in the hopper with the binding margin on the top (or bottom) side, the cut sheets placed in the hopper by the printing device will not have binding holes. If this is notified to the higher-level system, the higher-level system can recognize that printing is on unbound cut paper, and can also know the paper feed direction of the cut paper from the binding margin position and the paper size in the printer information. Therefore, the printing direction can be designated to the printing device by referring to the printing direction setting table shown in FIG.

As described above, the present invention sets the cut paper in the hopper so that the binding margin position is on the upper (or lower) side, and changes the printing direction during single-sided printing to correspond to the printing direction during double-sided printing. This allows the binding margin positions of the cut paper printed on one side and the cut paper printed on both sides to be the same.

Hereinafter, the means adopted by the present invention to solve the above-mentioned problems will be explained with reference to FIG. FIG. 1 shows a principle diagram of the present invention.

In FIG. 1, reference numeral 10 denotes a printing device, which has single-sided and double-sided printing functions, and performs single-sided or double-sided printing of print data sent from it under the control of a host system. Also,
Binding margin position information indicating the binding hole position of the cut paper set in the hopper is notified to the host system along with other printer information.

20 is a host system equipped with a host computer, which controls the printing device 10 to perform single-sided or double-sided printing. In the host system 20, 21 is a printing direction control means, which controls the binding margin of single-sided printing and double-sided printing based on the designated printing method, printing direction, binding direction, and binding margin position information notified from the printing device 10. Control is performed to set the printing direction so that the positions are the same.

The present invention is implemented by the system as described above, and is configured as follows.

In other words, the upper system (
20) In the single-sided and double-sided printing control system in which print data is sent from the printer and printed in a predetermined binding direction and printing direction, (a) the printing device (10) responds to a printer information request from the host system (20); (b) The host system (20) notifies the upper system (20) of binding margin position information that instructs the paper feeding direction of the cut paper (12) along with other printer information; Based on the printing direction, the binding direction, and the binding margin position information notified from the printing device (10), the printing direction is set so that the binding margin position for double-sided printing and single-sided printing in the print result is the same, and the printing device (10) 10), configured as follows.

[For production]

The operation of the present invention will be explained with reference to FIGS. 1, 3, and 5.
The following will explain the control procedure.

■ On the printing device 10 side, the binding direction of each cut sheet is upward (
or lower) side and set it in a hopper (not shown). In this description, it is assumed that the hopper is set in the upper side.

In this case, the printing device 10 determines the direction in which each cut sheet is set in the hopper without being aware of the printing method, single-sided or double-sided, or whether there are binding holes in the binding margin of the cut sheets. You can do the same. Therefore, in principle, only one hopper is sufficient for setting cut sheets.

(2) The host system 20 issues a command to the printing device 10 to request printer information.

(2) Upon receiving this printer information request command, the printing device 10 notifies the host system 2-0 of binding margin position information indicating the binding margin position of the cut sheet set in the hopper, along with other printer information.

■ The printing direction control means 21 of the host system 20 performs one-sided printing regardless of the presence or absence of binding holes based on the printing method, printing direction, and binding direction specified by the user as well as the binding margin position information notified from the printing device 10. Control is also performed to set the printing direction so that the binding margins for double-sided printing are the same.

This setting of the printing direction is performed by referring to the printing direction setting table shown in FIG. 3 mentioned above if there are binding holes, or by setting the printing direction shown in FIG. 5 mentioned above if there are no binding holes. This can be done by referring to the table.

(2) The host system 20 instructs the printing device 10 to print the printing direction set by the printing direction control means 21.

(2) The printing device IO performs single-sided or double-sided printing with or without binding holes in accordance with a new printing direction instructed by the host system 20.

This allows printing results with the same binding margin position to be changed between double-sided printing and single-sided printing. (
(Details will be explained in the Examples section.) As described above, the printer side sets each cut sheet in the hopper with the binding direction facing upward (or downward), and transfers the binding margin position information to the upper Based on the binding margin position information from the printing device, the higher-level system sets the print direction so that the binding margins for single-sided printing and double-sided printing are the same, and sends it to the printing device, and the upper-level system Since printing is performed according to the print direction specified by the system, there is no need to change the print data or cut sheet setting direction on the printing device side for each printing method of single-sided or double-sided printing. By automatically performing single-sided printing and double-sided printing in accordance with the designated printing direction, the binding margin position after printing can be made the same regardless of the presence or absence of binding holes.

This basically eliminates the need for multiple hoppers for single-sided printing and double-sided printing on the printing device side, and eliminates the need to be aware of the printing method, printing direction, and presence or absence of binding holes in the binding margin. The burden and work on the operator on the device side can be reduced.

Furthermore, since the binding margin for single-sided printing and double-sided printing can be the same,
The load of post-processing on the printing device after printing can be reduced.

(Example) Examples of the present invention are shown in FIGS. 3, 5, 6, and 7A.

Based on the margin position information, the printing direction is set so that the binding margins for single-sided printing and double-sided printing are the same, and the setting is sent to the printing device, and the printing device prints according to the printing direction specified by the host system. Therefore, without having to change the print data or cut sheet setting direction in response to each printing method of single-sided or double-sided printing on the printing device side, the printing device can automatically perform single-sided printing and duplex printing according to the printing direction instructed by the host system. By printing, the position of the binding margin after printing can be made the same regardless of the presence or absence of binding holes.

(2) In principle, there is no need to provide multiple hoppers for single-sided printing and double-sided printing on the printing device side, and the printing method
Since it is no longer necessary to be aware of the printing direction and the presence or absence of binding holes in the binding margin, the burden and work on the operator on the printing device side can be reduced.

(3) Since the binding margin for single-sided printing and double-sided printing can be the same,
The load of post-processing on the printing device after printing can be reduced.
