2. Description of the Related Art Conventionally, as a method of preventing page misalignment when paper jam occurs in backside printing when performing double-sided printing with a printer having only a single-sided printing mechanism, for example, a technique described in Japanese Patent Application Laid-Open No. 9-6074 is disclosed. There is. According to this technique, when a paper jam occurs during backside printing, the remaining pages are printed without jam recovery, and after the printing is completed, both sides of the page where the paper jam has occurred are printed.

FIG. 3 is a flow chart showing the operation when performing double-sided printing with a conventional printer. First, in step 11 (hereinafter abbreviated as s11), the page count is set to 1, and in s12, it is determined whether front side printing or back side printing.

At the time of front side printing, after the discharge port is face-up in s13, a command for performing jam recovery is set in s14, and when a jam occurs, the jam recovery is automatically executed. At the time of printing on the back side, after the discharge port is set to face down in s15, the command for performing the jam recovery is released in s16, so that the jam recovery is not automatically performed even if a jam occurs.

Next, in s17, it is determined whether or not all pages have been printed out, and if so, this routine ends. In step s17, if all pages have not been printed out, in step s18, the print data of the page is developed,
In s19, this expanded data is transferred to the printer engine, and the flow returns to s17.

When a jam occurs during backside printing, a page number obtained by subtracting 1 from the jammed page and the jammed page are stored, and the remaining pages are printed without performing jam recovery. After this printing is completed, print data for front side printing and back side printing is generated from the page number obtained by subtracting 1 from the jammed page and the number of the jammed page, and double-sided printing is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a functional configuration of a printer that performs booklet printing according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes input means such as a keyboard and a mouse, which are used by a user to designate printing conditions for booklet printing by key input. The printing conditions specified by the input unit 1 are analyzed by the printing condition analyzing unit 21, a booklet printing specifying unit 22 is created, and a printing result of booklet printing based on the conditions set by the print data generating unit 23 is output to the printer 3. Is what you do.

The booklet print setting is analyzed by the print analysis unit 21 through the input unit 1 and sent to the booklet print designation unit 22. The booklet print designation unit 22 sends a page layout condition to the print data generation unit 23 from each set value such as a page range and a paper size. The print data unit 23 generates print data, sends a print job to the printer 3, and executes printing.

Next, the operation of this embodiment will be described with reference to FIG.
This will be specifically described with reference to the flowchart of FIG. First, it is determined in step s1 whether printing to be performed is partial booklet printing for compensating for missing pages or the like or normal booklet printing.

In the case of ordinary booklet printing, layout conditions are adjusted based on set values such as paper size and page range.

In the case of partial booklet printing for compensating for a missing page or the like, layout conditions are adjusted based on set values of a paper size, a page to be compensated, and the like. When a page is designated, a print area of the document to be printed necessary for the layout is designated and sent to the print data generating means 23.

Now, assuming that the total number of pages of the document to be printed for booklet printing is N, the number of prints M is M = N / 4 if N is divisible by 4, and M = N if N is not divisible by 4. (The integer part of N / 4) +1. here,
The page of the document to be printed is called a page index for convenience. In order to designate a page to be compensated for a missing page or poor printing by the number of pages, if this page is the P-th page, the page index required for the layout is 2P-1, 2
P, 4M-2P + 1, 4M-2P + 2, and 2P-1
And 4M-2P + 2 are laid out on the front side of this paper, and 2P and 4M-2P + 1 are laid out on the back side of this paper.

When designating a page to be compensated by a page index, if the designated page index is K, the page indexes required for layout are K, K + 1, 4M-K,
4M-K + 1, K and 4M-K + 1 are laid out on the front surface, and K + 1 and 4M-K are laid out on the back surface. The designated page index is not K, but K + 1, 4M
Any of -K and 4M-K + 1 may be used.

For example, if the designated page index I is I = 4M-
If K, the page index required for layout is 4M
−I, 4M−I + 1, I, I + 1. in this way,
The printer according to the present invention has a configuration capable of performing booklet printing of a page designated so as to obtain a desired output result by a user for correcting a page due to dirt or tear of a page or replacing a page by correcting a sentence or character.
