Also, if you've been using the printer just before changing the ribbon cartridge, be careful not to cartridge rests OR the support ridge on the carriage and that the ribbon passes between the print head and the silver ribbon guide. 7 Release the tabs

    the example programs in this manual are written in BASIC. The data you send to the LQ2500, however, can be in any form (binary decimal, hexadecimal) that can be used with your programming language. After you've designed a character on a grid and translated the dots to decimal equivalents, the last

    . The command to define characters is one of the most complex in the LQ-2500s repertoire. The format of the command is: ESCape '&" 0 nl n2 d0 dl d2 data The EXape '&" is simple enough. The 0 (which is ASCll code 0, not the numeral zero in quotation marks) allows for future enhancements. At this

    patterns for each character. Since it takes three bytes to specify the dots in one vertical column of dots, the LQ-2500 expects d1 x 3 bytes of data to follow d2. An example character definition program should make this clear: 10 LRINT CHR$(27)"x0" 20 LPRINT CHRS(27)"&"CHR$(0); 30 PRINT "@@?'; 40
