hi, i have a thermal printer and id like to know how could i print qr codes or bar codes just using arduino, its meant to be use as an entrance check in , and i would like to use just arduino not pc.is it posible to generate them just in the code?
thanks and sorry for my english.

It is certainly possible, if you know the proper codes to send to the printer, if you know how to send the codes, and if you know the electrical connections to the printer. Do you know these values?

i allready print values, im not asking how to print or to do the conections , i would like to understand how to generate a qr code in the ticket i allready use just by using arduino, not excel, not a website, just by the code i compile, and if someone allready does it if he could share his experience.
Assuming they go to the printer as images that's going to be tricky to do on a basic Arduino due to the small 2 kB RAM.
Look at a processor with more memory - such as the ESP8266 or the Teensy. Those have much more memory and processing power available.
