i am a complete newbee on arduino and i would like to ask for help for printing serial from the arduino with an epson receipe printer. I would like to use the arduino kind of "standalone" connected directly to the printer.
the printer itself is ESC/P compatible andIi know the wire-ing of its serial port.
Do you know the voltage of the serial signals, that is :- is it TTL or RS232 voltages. If the latter you will have to boost the Arduino's serial output with something like a MAX232 chip. After that it's plain sailing, just set up the appropriate baud rate and send the data using serialPrint().
There's a lot of interest in the small Epson and Citizen thermal printers used with cash registers and the like. They call them "microprinters", and they have a Wiki:
Yes thank you, but unfortunally they are all taling about other types of printers. mine is a epson TM-U220 which is using ttl serial. can anyone tell me or even better show how to wire from the arduino´s outputs to the serial plug?C:\Users\MarkusB\Documents\PrintScreen Files\TM-220serialConn.jpg
