Hi,
I am developing the serial printer adaptor to connect the host PC to printer through serial port. I am using a microcontroller to convert the serial port interface to printer port. I need your help about the following two topics:
1. What are the commands printer send back to the microcontroller. Is there any spec that I can refer?
2. How can microcontroller converts the command and then send back to host PC?
Beest regards
Frank
