How to create qr code based on 30 digit number and send the generated qr code to wireless printer.

  • Answer: By doing a bunch of research, finding a C++ library that generates QR codes, an Arduino that has wireless, a wireless printer library, and then writing a bunch of code. Note this is is probably more than you could do with an AVR based Arduino. you'll probably need an ARM-based Arduino, since those have a lot more memory and processing power. (AVR-based arduino's are memory starved) – Duncan C Aug 29 '20 at 1:03
  • Or could we do this way! lets say we have 30 digit code and QR code containing files. We compare the 30 digit code with codes in file, if they tally then print that qr code in that file to printer. Is this possible? – dkpuvvula Aug 29 '20 at 11:35
  • Or can we use raspberry pi instead of arduino i guess ,which we will have wifi connection. We can generate qr code using python and save it in to a file and print those file using wireless printer. Is this possible? – dkpuvvula Aug 29 '20 at 12:21
  • why don't you generate the QR code online? ... this is not really an arduino question ... if I was doing this, then I would develop the python code on a PC and then run it on an RPi – jsotola Aug 30 '20 at 0:46
