Introduction

============

PrintGrandma is a simple implementation of an automatic thermal printer system for pictures made for my grandmother, inspired by [Yayagram's project](https://github.com/mrcatacroquer/yayagram). You can find more of Yayagram project in [instructables](https://www.instructables.com/Yayagram/).

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.
