Printing Technology: It is a 9-pin, serial impact dot matrix printer, which means it uses a ribbon cartridge (Epson ERC-38 in black or black/red) and plain paper rolls, rather than thermal paper.
Model Type: The "IIB" in the model name indicates that it has an auto-cutter mechanism, but does not include an auto-winder, in a compact, box-style form factor.
Connectivity: This specific model uses a serial interface (UB-S01) for connection to a computer or POS system, as well as a D.K.D. (drawer kick-out) port for connecting a cash drawer.
Paper Handling: It accommodates various paper widths (57.5mm, 69.5mm, or 76mm) with a maximum diameter of 83mm.
