mini thermal receipt printer

online shops

  • coolcomponents have a battersea pickup. email them and should be able to make arrangements within 3-4 hrs sameday.
  • proto-pic is from scotland so no pickup but their standard 1st class delivery is 2 working days which is very decent.
  • alternatives:

Working script - truth.ino
