Hi. I am curently using Crystal Reports for POS printing but if printer is connected on any port other than USB it takes 10-20 seconds for printer to complete printing the receipt. Of course, over USB is almost instant, so I guess that problem is in big report and slow communication cable.
I was playing with sending strings to printer and that is working, but i have to create bunch of strings for many reports that will need to be printed.
My question is, do you know of better way for POS printing over serial, parallel cable (fast printing, controling drawer, Buzzer, Cutter...). Maybe ready to use module (I don't mind if it cost me something to have quality solution, and learn something in the process)
