We are developing a prototype. We use an Atmel 8-bit AVR microcontroler Atmega2560.
Goal is to generate a QR Code of an arbitrary alphanumeric text of about 500-1000 characters. And this QR Code should be provided as an image in ESC/POS printing sequence (Printing command ESC * m nL nH d1...dk).
So the result would be a byte array which holds that ESC/POS command.
So steps are:
1) input is alphanumeric text. Character Set ISO-8859-1, Level Q.
To do: Generating a QR Code . output: QR Code, e.g. as bitmap.
2) input QR Code. Todo: transform to ESC/POS sequence ( ESC * m nL nH d1...dk), which sends the QR code as image to a receipt printer (E.g. Epson printer TM-T88V) . Result: printer prints the qr code onto the receipt.
As the code should run in a 8-bit AVR Microcontroler, the code should be provided as AVR C Source code. Could be tested e.g. on a Arduion board.
If you are not able to provide AVR C code, next best would be standard C with only standard libraries, so that we easily can transfer it to AVR C. In latter case we have to agree on a reduction of the salary.

Sir, I have experience using AVR microcontrollers. I'm confident I can resolve your issue, as I have a engineering degree(automatics). Let's discuss further details about this project.
Hi. I have lot experience with those Epson printers and those ESC codes. Also, I know how to code and decode a QR code. Let's talk about the details. Best regards, Monillo
Hello Sir Thanks for post, here we have checked your complete details and review it, after review we have some queries in it. So please message us to discuss on it more to clear it and start project. Thanks
