Epson T20 Guest Receipt Printer Troubleshooting & Info

This article applies to the Epson T20 thermal printer. There is a newer model in use, called the T-20II and the T-20III. Please do not confuse them. While they look the same, some of the details between the two are different.

The T20 has the power supply built in to the printer. There is no need for an external power brick. The T-20-II and T-20-III printers require an external power brick.

The T-20 line of printers (I, II & III) do NOT have changeable interface cards.
