JPH078586B2 - Print control method for hand-scan printer - Google Patents

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand scanning printer (also referred to as a handy printer) for holding a print head by hand and applying it to a paper surface for printing.

<Prior Art> A hand scanning printer is used, for example, in combination with a word processor or the like, and prints a character string input in the word processor on a paper surface. It can be printed at any position.

<Problems to be Solved by the Invention> In the conventional hand-scanning printer, since a character string that can be printed in one scan is only one line, the number of scans is large when a large amount of text is printed. However, there are problems that the work is complicated, it takes time, and the hands become tired.

For this reason, a hand scanning printer has been devised which can print, for example, two lines in one scan. However, in this hand-scanning printer, it is necessary to detect the end of one of the two character strings in order to finish the printing.

<Means for Solving the Problems> The present invention relates to a hand scanning printer in which a print head is manually held and scanned on a paper surface to print a plurality of lines of character strings on the paper surface in one scan. The line feed code of the longest character string of a plurality of character strings is detected as the end of the print data and the printing is terminated.

<Operation> In the present invention, the line feed code of the longest character string of a plurality of lines of characters is detected and printing is terminated. Further, when the character strings of a plurality of lines are all the same length, when the line feed code of the character string of the first line is detected, the printing ends.

<Example> FIG. 1 shows a functional block configuration of a method of the present invention. The number of characters in the first line is counted by the counter 2 from the first line character string data input by the first line character string input unit 1, and the second line character string data input by the second line character string input unit 3 From the counter 4, the number of characters in the second line is counted. The count value C1 of the counter 2 and the count value C2 of the counter 4 are compared by the comparison unit 5, and according to the result of this comparison, the print end detection unit 8 detects 1 by the line feed code detection unit 6 when C1> C2. The line feed code of the second line character string is detected as the end of the print character data. When C1 <C2, the line feed code of the second line character string detected by the line feed code detection unit 7 is detected as the end of the print character data.
When C1 = C2, the print end detection unit 8 detects the line feed code of the first line character string as the end of the print character data.

FIG. 2 shows an example of the operation. Since the count value C1 in the first row is 9 and the count value C2 in the second row is 12,
Printing ends with the line feed code (12th character) on the line.

FIG. 3 shows the processing procedure. First, the character string in the first line is fetched and the number of characters is counted (# 1, # 2).
When the count value C1 is equal to the predetermined number of characters for one line, a dummy line feed code is added (# 3, # 4). Next, the character string in the second line is fetched and the number of characters is counted (# 5, # 6). When the count value C2 is equal to the predetermined number of characters for one line, a dummy line feed code is added (# 7, # 8). When the count value is C1> C2, the line feed code of the first line is the end of printing (# 10). Count value is C1
When <C2, the line feed code of the second line is used as the print end (# 11). After that, character codes are taken out character by character from the character code buffers on the first and second lines (# 12), and the character pattern data corresponding to the character code is read from the character generator (# 14). ), The character pattern is printed (# 15), the read address of the character code buffer is incremented (# 16), and the processes of steps # 12 to # 16 are repeated.

<Effects of the Invention> As described above, in the present invention, the end of the print line is detected by the line feed code of the longest character string of the plurality of lines, and the printing is ended. Can be eliminated and work efficiency can be improved.
