Note that there may be only one paragraph.

01 copy of document refers to a set of documents and refers to the entire document to be printed.

First, data is input from the KB2, a document is created and edited, and its contents are stored in the DBU5 in the form of a code such as a character code, but since this procedure is not directly related to the present invention, a detailed explanation thereof will be omitted. do.

However, at the stage of document creation and editing, the number of C/Hs is Cj
-1 (however, 1≦j≦a), and the number of characters in each paragraph therein is qji (however, l≦1≦Cj), each register PLNR of the DCR 12.

It is assumed that corresponding data is stored in C/RNR1 and PNER, respectively, as shown in FIG.

Next, the following steps are required when printing: ■Determine the size of the paper to be printed, ■Determine the left and right margins, and character pitch, ■Top,
Three types of printing parameters are set to determine the bottom margin and line pitch. This parameter setting means includes methods for directly setting character pitch and line pitch values, -
There are several options, such as specifying the number of characters or lines on a line or page, but they are not directly related to the present invention, so detailed explanations will be omitted. Now, by setting the print parameters described above, each person's printing surface Suppose that it is composed of M lines x N characters. Here, the number of C/H is C'-1, the 1st paragraph and 1+1 paragraph (however, 1≦1
Assuming that this is a series of documents in which the number of characters between C and R of ≦C is 91, the total number of characters in this series of documents is calculated by the following formula (11).

1 is a whole.

Therefore, the number of characters counted from the first character of this document to which the first character of the second negative mark (1≦P≦S) of this document corresponds is determined as follows. In other words, the number of lines required up to P-1 negative is CP-1)M lines, so the following formula (4)
The least 1 and X that satisfy. In other words, the number of lines required up to the P-1 negative line is the sum of the number of lines up to the 1o-1 column vertical line and the number of lines up to the (m□-x6) line of the 1° paragraph.

Then, the following equation (5) is obtained.

Number of letters m/ql. is the number of characters in the first paragraph, Hz is P-1
This is the number of characters remaining in the 1st paragraph after printing up to the last line of the negative number, so (q . - Nx), .

This is the number of characters used up to page P-1 in the paragraph.

Therefore, the first character of the second negative is the k+1st -1 character. □Now, the character codes of this series of documents (codes of character codes, etc.) are stored consecutively from address A in DBU5. Assuming that

The following formula (8) is used. .

A (P) thousand to ten, + to' (8) jn oo 3-1j (p-1) Furthermore, the continuous page PPj is given by the following formula (9), and the total number of pages T is given by the following formula (
II is round. , As mentioned above, by setting the printing parameters,
Using the above formula (11 to α1), calculate the total number of printed pages T and the storage address Aj (Pxi) of the code such as the first character of each member as CP.
Calculated using the UI. At this time, the numerical information used in the above equations (1) to (11) is stored in the DC!R 12 and used as data.

The values calculated in this way are shown in Figure 3, from 5 to 0 to B.
, 8 data areas of HLAP (each true first character code address pointer) whose address is +T-1, and TPNC.
(total page number counter) 9.

Next, when a key to start printing or a command instructing to start printing is input by KB2.

CPUI is the data content Aoo+Ka-x+ka of address B0+T-1 of HLAP8 corresponding to the value of TPNC9.
The content of (s)-1 is extracted as the first character of the page, and the characters after that address are sequentially printed on paper (output paper) by the PRT7.

At this time, each time a - character is printed, the FCC (print character counter) 10 is counted up by '1', and the value of pccio becomes the number of characters in one line, N. However, if there is a C/R, the PCC

Counts up only IN. Then, when the value of PLCII is the maximum number of rows M for each member and the value of p c c i O is N, or when there is C/R, and PLCII
Regardless of the value of P or P CC10, if P or E is found, printing of that page is finished.

When the printing of one page is completed, TPNC9'11"1" is printed, and the above-mentioned operation is repeated. Finally, T.P.
The value of NC9 is the start address B of HLAPFI.

If it matches, print that page and end the printing operation.

With this, it is possible to sequentially print out a printed matter such as a fixed form document that spans multiple pages, starting from the last page and ending with the first page. Therefore, according to this embodiment, the topmost printed surface in the paper output tray (not shown) after output is the first page, and the last page overlaps the bottom, so the page order is There is no need to rearrange the documents (it eliminates wasted human time when creating documents, making it easier to use).

As a means of obtaining the code address such as the first character of each member, in addition to the above-mentioned formula (8) (calculating means), it is also effective to use temporary printing without actually printing. To explain the method, first, after clearing PCCIO and PLC11, DBU5 clears the first address where the first character code of the first page is stored.
It is stored in the B0 address (second self reference) of fLAP8, and then the DBU5 is trayed in order from the 17th address, and the PCC10 and PLCII are brought up in the same way as described above. - After tracing a page, the next D
Address of BU5) (Stored in address B+1 of LAP8. This operation is repeated in sequence, and when tracing of all documents scheduled to be printed is completed, the page number T is stored in TP and NC9. However, actual printing is Instead, only the processing of various memories and quanta is performed.Even with these five temporary printing means, the same results as the above-mentioned calculation means can be obtained.

〔effect〕

As explained above, according to the present invention, the address of the first character of each member is selected according to the printing parameters, and a multi-page document, etc. is printed out from the last page based on that address. Therefore, it is possible to eliminate waste when creating documents.
