Abstract

PURPOSE:To improve the operability in terms of print conditions by calculating the relation to the paper width and displaying the margin value when the left/ right margins, the number of characters and the character pitch are given as the print conditions. CONSTITUTION:The left margin L, the right margin R, the number of characters of a line N and the character pitch P stored in a memory means 12 are transferred to registers 13-16 respectively. An adder 17 adds both margins L and R together and supplies this sum to an input terminal of a subtractor 21. A multiplier 18 multiplies the number N by the pitch P and supplies the result of this multiplication to both a comparator 23 and a subtractor 22. A subtraction (B- A) is carried out by the subtractor 21 between the output A of the multiplier 18 and the paper width B. The comparator 23 decides whether the amounts of left and right margins are insufficient. Then the output of the subtractor 22 is displayed in the form of the possible maximum margin amount.

However, paper width B, left and right margins LR, number of characters in one line N1
When the character pip P becomes B-(L+R)<NXP・(11), it becomes impossible to print one line (two characters N pieces).

In conventional devices of this type, warnings were given only with ambiguous expressions such as ``Paper width is insufficient'' or ``Please reduce the margins.'' Therefore, in such a case, it is necessary to change the margin value appropriately.
In addition, such changes had to be made multiple times, resulting in very poor operability.

clOl is a document memory that temporarily stores the character code strings constituting the existing document in the storage means C21, and this memory is constituted by a high-speed memory such as a semiconductor RAM (random access memory). In addition, the storage of the above character code string is performed by the control signal C1 from the storage means (121) and the document memory (4-). This document memory diagram, character generator C311 and printer (1 bell is a control signal C
At t11, the character codes in the character memory (q) are sequentially converted into a pattern by the character generator C31+, and outputted by the pattern printer (l).

First, in step S1, data writing and paper width detection are performed based on control signals C1 and C4.

Specifically, the storage means 021 is stored in advance based on the control signal 01.
The left margin L, the number of characters N1 characters pip P in the 11th line of the right margin R, and a series of character codes stored in the 11th line are read out and stored in the first to fourth registers t13i and the document memory 001, respectively, and the control signal 04 (2) Based on the paper width setting means ρO, the width B of the paper set in the printer ri□□□ is detected. At this time, the left margin L, the right margin R, the number of characters in one line N, and the characters and
is also output to printer a9 (2) as the printing condition.

In step S2, addition processing and multiplication processing are performed in the adder t11) and the multiplier α12, respectively, based on the control signal 02.0642. Addition processing is performed in the first and second registers 1
Left margin L stored in 13+141, respectively.

The right margin R is added by an adder (17), and the sum A is output to one input terminal of the first calculator 12D. The multiplication process is performed by multiplying the number of characters stored in the third and fourth registers II 5) (L) by the character pitch P. The result M is multiplied by the character pitch P. ) and one input terminal of the second subtractor +221 (=output).

In step S6, the first,

Output to one input terminal of 4. In the second calculation process, the output M of the multiplier 08 and the paper width B are put into the second subtractor Cl to perform the modulus "B-M", and the result S2 is sent to one input terminal of the second AND gate ρe. Output to.

In step S4, comparison processing is performed based on the control signal c (white). In such a comparison process, the multiplication result M and the first subtraction result S1 are compared in a comparator (c). are outputted to the control unit aυ as comparison result signals C', respectively.

In step S5, the control unit aυ determines whether the comparison result signal d output from the comparator is "0" or "1".

As a result, when the signal is "0", the process proceeds to step S6, and when it is "1", the process proceeds to step 87.

In step S6, the printer (11) starts a printing operation based on the control signal o11 (2). This printing operation uses the pattern sent from the character generator G11 according to printing conditions C such as left and right margins LR1 number of characters N1 character pitch P;
This is a normal printing process carried out in response to alligators.

Further, in step S7, the following message output means is performed based on the control signals 05, C9, and O10 (2).The control signal C9 causes the message storage section +25 to be transferred to one of the first game H6). Input terminal (2 outputs, and control signal 05 (1st, 2nd from 2)
The AND gates C2 and 2D are both opened (2 open), and the above data and the second subtraction result S2 are passed through the above two gates respectively and are input to the synthesizer (2 minus 2). The signal is sent to the synthesizer (2) based on the control signal 010 (2).
& is synthesized and ORT Dinubrei (2J (=display output) and the process ends.

Next, in order to make the above operation easier to understand, we will specifically explain the processing operation when the left and right margins LR 1 number of characters N 1 character pip P and printer Hζ width B of the set paper meet the following conditions [11 (11)] explain.

At this time, it is assumed that the message storage section 29 (2 is ``Please keep the total value of the left and right margins below YXX mm''... the message ``Mountain'' is stored as data.

tll B-(L+R)<NXP At this time, in steps Sl to S4, storage means l'1
21, the left and right margins LR1, the number of characters N, and the character pip P are stored in the fourth registers (131-6), respectively, and the paper width B is also detected, and the adder n is stored.

In the multiplier (181, first and second subtractor 12 and comparator 1231, 'L+R', -NXP'', -B-
A”.

“B-M・,”81>M・ are processed, and the comparator C(
The comparison result signal C', which is the output of
Further, the output s2 of the second subtractor (221 is outputted to the AND gate 07). Next, in step S5, it is determined whether the value of the comparison result signal C1 is "0°" or "1." In this case, since "B-(L+R)<NXPo", the result is "1", and therefore The process proceeds to step S7 and ends. In step S7, the message of the mountain stored in the message storage section C51 and the output S2 of the second subtractor (22) are combined in the combiner +21D, and the message is displayed on the CRT display (9) (second subtractor). The message "Please keep the total value of left and right margins 't' below 82 mm" is displayed.

11i1 B-(L+n)≧Nxp In this case, the processing in steps Sl to S4 is as described in (1) above.
Since the conditions are the same as in the case of , the explanation will be omitted. Under such conditions, the comparison result signal Ql becomes "01", so the process proceeds from step 85 to step 86 and normal printing process 7 is performed.

In this example, the total value of the maximum possible left and right margins LR from the paper width B set in the printer, the left and right margins LR as printing conditions, the number of characters N1 and the character pitch P is displayed on the ORT display (2). It becomes possible to determine the left and right margins LR based on such display.

In this embodiment, the printing paper width was detected using the paper width setting means (2) built into the printer 0, but it was manually input using an input means such as a keyboard, and the input value (2) was detected based on the input value (2). C: may be configured to perform the processing below step.

Further, in this embodiment, the shortage of paper width is displayed on the RT display (29j), but the display C2 may be replaced with an audio output means (29j) to notify the user.

Furthermore, in this embodiment, the control unit 0111, the first to fourth registers 13 to ([6), the adder fi71, the multiplier 08), the first and second subtractors, and the comparators (two? Separate However, it may be constructed as a single chip using these Z microcomputers.

(F) Effect: Since the printing control device of the present invention displays the maximum possible total value of the left and right margins, changing such margins is extremely difficult.
