Info: Instruction manual, designed for use with Canon programmable desktop calculators.
The printer produces records of manual calculations, displayed results, stored programs, and programmed calculations.
It uses a drum printing mechanism with black and red ink; negative values are printed in red. Each line can contain up to 16 numerical digits, four symbols or codes, and a decimal point.
The manual explains how to connect the printer, operate its switches, load paper, and replace the ink ribbon. It requires paper approximately 89 mm wide, with a maximum roll diameter of 86 mm, and an EP101-type ribbon measuring 13 mm wide and 6m long.
Its main printing functions include:
Manual calculation printing: records entered numbers and arithmetic results,
Display printing: prints the calculator’s current display when no calculation is running,
Program listing: prints stored program steps, instruction codes, and symbols,
Program-controlled printing: prints data and results using stop instructions or dedicated Print and Paper Feed instructions.
The manual also explains overflow behavior and how to avoid duplicate printouts when combining print and stop instructions.
Worked examples demonstrate the Pythagorean theorem and the calculation of an average unit price from total cost and total quantity.
