1. Know Your Printer Model

Every calculator uses a specific ribbon type.
Always check:

• The exact model number (e.g., Sharp EL-1801V, Casio HR-200RC, Canon P23-DHV)

• Whether the device uses a spool ribbon or a cassette ribbon

• The recommended ribbon code (IR-40T, CP-13, EA-772R, etc.)

Model compatibility is the most important factor.

2. Choose Between Spool and Cassette Ribbons

Cassette Ribbons

Fabric Ribbons
