Introduction

PrintGrandma is a simple implementation of an automatic thermal printer system for pictures made for my grandmother, inspired by Yayagram's project. You can find more of Yayagram project in instructables. In my case, the printing is automatic. My grandmother does not know how to read, does not have a smartphone and it has to be the easiest that it could be, so it will not be bydirectional, just one way. Any of the grandson/grandsister can send a picture to the telegram bot, and it will be printed automatically.

Core functionality

• Telegram interface: to receive the pictures and save them for the printing queue.
• Thermal Printer interface: Control the printer

Future functionality

• Sound/Light notification.
• Voice message replay
