Yes as a sideline when not doing PCB's we can now do nameplates.........
I have since the earlier post removed the cover from the printer, it's
going to be a tough job making it 100% flat path, as some parts are

Anyhow, the printer wont work at the moment, says paper jam so I must
have knocked something, just downloading repair manual.............ho
