Tally Genicom Matrix Printer *1234* *1234*

7265 Programmer’s Manual 44

The HT control code (09) is a valid delimiter in all bar c ode styles. The leading quiet zone of a subsequent

symbol begins at the first tab stop right of the trailing quiet zone of the current symbol. This is evident in the

sample, where the quiet zone of the second symbol begins at the third tab stop.

Since this printer stores tabs in nonvolatile RAM whil e power is off, and since the control sequence that sets

horizontal tabs does not clear existing tabs, you should cle ar all tabs before setting tabs. Note also that new tab

stops do not take effect until you send a line terminator; in other words, you cannot set tabs for the current line.

The superfluous tab stops in the following example are incl uded to show you how the function works. If you use

horizontal tabs for delimiters, then set no more tab stops than you plan to use.

100 LPRINT CHR$(27);"[4;9;1}"; ‘3 of 9

110 LPRINT CHR$(27);"[3g"; 'clear all h_tabs

120 'set horizontal tabs at 1/2-inch intervals

130 LPRINT CHR$(27);"[360;720;1080;1440;1800;2160u"

150 FOR K = 1 TO 6 'show where the tabs are

160 LPRINT CHR$(9);"T";

170 NEXT K

180 LPRINT

190 LPRINT CHR$(27);"[3t"; 'turn on bar code

200 LPRINT "1234";CHR$(9);"1234";

210 LPRINT CHR$(27);"[0t"; 'turn off bar code
