I want to print QR codes for the products in a manufacturing plant. I could able to create till QR code. But, not able to find a way to print it.
Hi, How can I link this to the QR code generated in the MIT APP Inventor 2 and print it to the printer. Does this find the printer automatically? Is it Bluetooth or WIFI also?
I am really looking for solution. I have referred many:
Print of QR code using Bluetooth sending Bytes. Can I convert to Bytes and send it to Printer, So, QR code will be printed? I saw there is a text to pass on and printer is printing the text via bluetooth without any extensions. But, is it possible to send QR code to print using bytes approach? If so, I need help with blocks to place.
Do I need to use only Thermal printer? Not any other printer?
I want to see, if possible to use wifi or the atleast bluetooth. When I try to use bluetooth option in the MIT app inventor, it is not connecting the basic devices properly. IF so, how reliable it is to send print? They print continuously by scanning products in manufacturing plant during unload like in super stores.
Here is the printer planning to use. Does this extension support this printer:
