Calculator Printing Olympia CPD 425

The Olympia CPD 425 is a desktop printing calculator with a 12‑digit LCD display and single-line blue printing. It uses an ink roller (IR 40) and accepts paper rolls 57 mm wide with a recommended diameter up to 65 mm (maximum 110 mm). The device supports tax calculation, percent functions, memory for addition and subtraction, and a display/print selector. Power is provided by AC or four AA batteries (included), and a print/non-print button with automatic power-off helps save energy.

Advantages

The printer mechanism produces blue one-line output at a speed of approximately 1.6 lines per second (96 lines per minute). A delete-last-entry key and rounding switch simplify correction and finalisation of calculations. Cost–Sell–Margin calculation and TAX functions support typical office and accounting tasks, while the internal roll installation option for small paper rolls (diameter < 27 mm) adds installation flexibility.
