I have the Pic working with windows "Hyper Term." . But I Cannot Get a Receipt printer to do anything using a Pic micro.
Anyone know What data lines I need to enable are pulse (ex RTS, Cts, Dtr pins). Any suggestion ANYONE!

 

The printer will almost certainly use hardware handshaking, the ones going from the PC to the printer are DTR and RTS, those from the printer to the PC are DSR and CTS.

You might check the hardware for my PIC RS232 tutorial?, I manually link the handshake lines on the D connector.

Something else to be aware of is the fact that both your pic circuit and the receipt printer are both wired to connect to a PC. This means that they both expect to receive data on pin 3 and transmit on pin 2. If you connect the pic circuit to the printer then you end up with TX to TX and RX to RX. The solution is to have a cable that swaps pins 2 and 3 or an easier way is to swap them on your pic circuit.

hi, i am doing a similar project. can you tell me what serial printer/pic you used? and what became of the result?
