I can't get to any manuals on pos.epson.com w/o registering, so I'm only guessing here. I bet you need to somehow embed "\e" (not backslash & 'E', but chr(27)) into the pos_invoice.txt file. You can try: perl -e 'print "\e"' >> pos_invoice.txt from a linux command line. This will append one escape character to the pos_invoice.txt file, which you can copy and paste around to compose your escape sequences. I did manage to find: http://www.datamaxcorp.com/_assets/library/pdf/e3202_esc_pos_programmers_manual_d.pdf Which seems to summarize the escape codes available in ESC/POS. Also, it seems ghostscript supports ESC/POS as well. Convert your image to ps, (try the netpbm tools: pngtopnm < file.png | pnmtops > outputps.ps) then try: gs -sOutputFile=outfile.escpos -sDEVICE=escp outputps.ps and keep hitting enter (should only be once, I hope) place the contents of outfile.escpos in your pos_invoice.txt file, and i *think* it should work. Hopefully this is enough info to get you going. I don't have any POS printers to confirm that any of this works, this is just from doing a bit of research. Jason
