The Citizen CBM-910II is a palm-sized impact dot matrix printer for 58 mm plain-paper rolls – ideal wherever thermal paper is unsuitable: in hot kitchens, for receipts that must stay legible for years, or for printouts with a 2-ply copy. Weighing just 470 g and wall-mountable, it fits on the smallest counter or machine. This version, CBM91024RF2A, prints 24 columns of large, easy-to-read characters at 2.5 lines/s and connects via a serial RS-232 port (25-pin D-sub); it comes with a Citizen AC adapter and an EU (Schuko) power cord – the interface cable is not included.
