Post Net Bar code printing on Epson action 5000 printer
I would have to see your code to know exactly what you are doing
wrong. You cannot pass hex values to the CHR$ function. You need to
pass them using the syntax: Lprint Chr$(Val("&H1B"));
or convert from hex to decimal and pass the decimal value to the Chr$
function. Also, when you use the LPrint fuinction, there is an
implicit carriage return - linefeed added to every print unless you
put a semi-colon at the end of the Lprint function.
The company that I work for sells source code for printing bar codes
to any Epson printer - even ones that do not have bar code support
