Ready to use. Use adafruit library to connect with arduino. All wires included. External dc adapter 9v 2a required to supply enough power. 4 paper rolls included.

Overall, the printer is working, but it was printed unstable from the box; there were spaces and stripes periodically. I disassembled and sharpened it with an invoice in the head housing on both sides, into which a pressure drum is inserted when the lid is closed. Now it prints much better. I also asked the seller for a program for configuration and connected the Cyrillic to UTF-8, so printing Russian letters with graphics is not required.

Exactly as expected, appears to be solidly made.

The zip provided by the seller containing the drivers and documentation (not available in English) is detected as containing a virus.

Surprisingly fast delivery. Great quality.

Great little printer. Works well with the Adafruit Thermal Printer Arduino library. The Adafruit library doesn’t utilize the QR204’s embedded QR code functions though you can send the commands manually over a serial connection. Recommended.
