What is the proper paper replacement ?

An option like UNV35720 would be best suited for the P170-DH-3 Printing Calculator.

Other 2 1/4" paper roll options will also work with this device

Hello, I am interested in knowing how a paperless calculator prints?

The calculator does not actually print, you are able to view the entries on the screen. You are able to scroll up and down to see up to 300 Entries (Instead of looking at paper)! This calculator also has a Check and Correct feature which allows entries to be modified on the screen.
