Hi all,
Currently, I am working on a project where I want to print several images over the ESC/POS EPSON TM20-III Printer.
The Printer is connected to the second USB pin on the Teensy 3.6. I am using a breakout board USB A female directly soldered with its pins to the Teensy 3.6 ports.
I am using those libraries to connect with the printer;
https://github.com/gdsports/ESC_POS_Printer
https://github.com/gdsports/USBPrinter_t36
In the USBPrinter_t36 example file, Printer.ino, the printer gets found --
Unfortunately, it does not print anything by sending anything on the Serial or adding .write() within the code.
---
Additionally, I tried the examples of the ESC_POS_Printer library, where in the beginning 1 or 2 lines were printed (not everything), and currently, it does not print anything anymore.
Has anybody any tips on how I can possibly debug what is going on?
