Adafruit Thermal Printer

Post by JustinT47 »

Hi Guys (and girls),

I'm trying to use my new Adafruit thermal printer but not having much luck.

I'm using a PIC16F877 running a 20MHz clock. The PIC is working and I'm running a serial LCD ok, albeit at 9600 baud.

When I output a 19200 signal to the printer I get absolutely no response. The LED on the front of the printer is blinking continuously regardless of the connection to the PIC.

Does anyone have one of these printers working with a PIC? Anyone know about parity and stop/start bits?

Thanks for your help.

What is the baud-rate reported by the self-test. Some printers are 9600. Other parameters should be:
No parity, 8 data bits, 1 stop bit.

I am having the same problem .
I am using an atmega8 USART.
Did you solve the problem?
