hippy Technical Support Staff member Feb 23, 2020 #2 It seems the printer is controlled by serial, 9600 or 19200 baud, using Escape Codes to configure the device. I couldn't find a link to any specific datasheet for the product though they say all their printers work the same code-wise, so these may apply - http://www.adafruit.com/datasheets/CSN-A2 User Manual.pdf http://www.adafruit.com/datasheets/A2-user manual.pdf Their library code library seems to be here - https://github.com/adafruit/Adafruit-Thermal-Printer-Library/blob/master/Adafruit_Thermal.cpp Adafruit may have additional information on their product. It might be worth contacting them.
