Hello Developers,
EXTENSION DESCRIPTION
I have created an ESC/POS Thermal Printer Extension. This can print text, images, lines and QR codes. I have noticed a high level of community interest in this functionality but have not yet received any responses.
So, I’m happy to share this extension which can print at a very affordable price.
