|Yeh, I don't think it's a gwbasic issue so much as a printer-control issue. I use qbasic to send esc-codes to set up my epson dot-mat for various sizes and fonts. It's quite simple (I'll add line no.s for gw compat):|
'set up printer for big printing
20 E$ = CHR$(27)
40 OPEN "LPT1" FOR OUTPUT AS #2
50 'Note: 3A sets vert. pitch to A, change for desired preference (A=asc.65
60 ' and represents 65/180ths inch)
70 PRINT #2, E$ + "@" + E$ + "W1" + E$ + "w1" + E$ + "3A";
90 PRINT "PRINTER IS NOW SET TO BIG FONT: 5CPI, 4LPI (5/16)"
But, as has been pointed out, you need to tailor the codes to your printer make/model, this just works for ESC/P (Epson-based) printers.
