When did they remove Printer ports from smartphones? Or did they? In any Case Clem has a dot matrix printer from the flea market and wants to print from his phone!

We see an Arduino Uno powered prototype, transfer the concept to custom hardware, cover some bumps in the process and write some code to make it work!
