Microcontroller | Mini Thermal Receipt Printer | Adafruit Learning System
I’m a bloody newbee in this group and I need some advise:
I’m trying to connect a thermal printer  to the ESP8266 (Wemos d1 mini) via a level converter . The thermal printer works fine if I connect it to an arduino but it refuses to print something with the ESP8266 (even If I change the timeoutWait function ).
Any hints what can go wrong? Thanks in advance 🙂
