Is the hr-100tm ink roller compatible with casio hr-170rc model ?

I have a Casio HR 100TM, don't know if the ink roller will also fit the HR 170rc model

How long does a cartridge last typically?

It greatly depends on usage and it is very subjective as to when the print is "light" but I would estimate a few months on average is a fair estimate for medium use.

Replacement rollers for Casio calculator

These are great inexpensive replacement heads for the Casio HR-100TM. They don't seem to last exceptional long but I do a lot of printing on the calculator too.
