This printer uses a thermal (heat) process to print on special (thermal) paper. Thermal paper is slick, shinny-coated paper. The printing can become unreadable over time.
The paper is a non standard size (both roll and sheet).
The printer does work with and Ax, but it does not work the same as your desktop. Only certain things can be printed “directly”, others must be copied.
I bought one because it sounded neat and the price seemed really low but I haven’t used it for anything practical, yet.
Look at
www.overstock.com before buying on eBay; the after S&H cost may be less.
