It is a Epson TM-U220PD. The software I am using sends esc. codes to the parallel port, so I can't change the printer nor use a parallel/esb cable nor convert the printer to USB. I think the problem is that the PCI card installed a LPT3 port and the printer is looking for a LPT1 port. I am so confused!!! When I try to print there is no error message, just the document won't print.
