Dear sirs
I have an experience in creation and modification of front-end software in retail since 1998.
As one of the tasks, I had to write the modules for termoprinters for printing the labels and stickers, including the barcodes and QR-codes.
Also, I have a very good experience in programming for AVR controllers and Arduino boards.
I can combine that skills for that project.
I will need several days on the next week to obtain a thermoprinter, compatible with your model for prototyping.
Please, feel free to contact me in chat.
With best regards
Maxim Bulkowsky
