I recently bought a nano thermal printer from adafruit to complete a project but I am having troubles with the printer. I though I had wired it up right on my Raspberry Pi A+ but wasn't able to get it to print a test page off the Raspian Jessie OS. I know the printer works because I can print the information sheet by pressing the button on the back. I have switched the RX on the printer to the TX on the pi and vice versa. I installed CUPS on another raspberry pi and put the SD card back in the A+ and still no luck. Theres lots of information on the tiny thermal printer not much info on the nano thermal printer. If anyone finds anything it would be a great help!
Thanks in advance,
