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

asked by Jae on December 19, 2017

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.
