Thermal Printer

[Normnet]

Why not use a standard printer by use of the Serial to Parallel-Printer Converter IC?
Else a mini serial dot matrix printer.
Or browse CUSTOM AMERICA Inc.
Also How to print to HP laserjet 1100 series using PIC without PC?
Or try some code:

I like thermal printers because they dont need any inc or ribbons to work. Just throw in the paper roll and start printing. Bad thing is that the text will fade after some time ..

Also the printout is cheap and good looking.
