Extended information:

The ribbon is generally made of nylon and coated with ink. Dot matrix printers use dot matrix strikers in the printer head to hit the printing ribbon to produce printing effects on the printing paper.

A good ribbon not only provides good printing results, but also reduces printer wear. The quality of ribbons mainly depends on three aspects: ribbon base (material quality), ink, and interface. Of course, after-sales service issues cannot be ignored.

In order to save costs, if the ribbon is used up, you can keep the ribbon rack, buy a corresponding style of ribbon core and replace it, and you can use it like a new ribbon (provided that the ribbon rack It is intact and not deformed).
