Hello! I need help on how to connect Arduino Uno with bluetooth module to a bluetooth thermal printer. My project is a bidirectional visitor counter with a queue number to be printed by a thermal printer. While I have already made a program for the visitor counter, the problem is connecting the bluetooth module and the bluetooth thermal printer and creating the program for it. I did several hours of research but all I saw where wired versions while it was easier, I don't have the confidence to assemble it and I might get the wrong printer , thus ruining the project and waste money. Is it possible to connect arduino Uno and thermal printer via bluetooth? And if I go for a wired version, what thermal printer should I buy (I can't afford Adafruit mini thermal printer and it might also be not available in my country)?
You need to know what protocol your thermal printer expects…
