>i have LX-300 printer, please please send me the code.
I looked all over my archives, and can't find it. I found the app which read them, but the little utility which printed them is lost. It was in use only for a few months, anyway, and then the shop was closed. We were too far ahead of time then :).
I think we used some sort of DOS utility which created a file with escape sequence. I may try a place where such a thing can still be found - later today, busy now.
[update] I looked it up and it's not there. Google for DOS barcode print, then.
