I need to send a character directly to the paralel port
I'm working with a Point of Sales program... the printer is an Epson TM-U200 and the ticket is in Qreport... well the problem is that I need to send a special character to the printer if I want to open the cash drawer, and I don't know a command or instruction that can send a letter (in hex)...- poderosocarlos
