Today's technology now allows you to create your own custom keyboard templates for cash registers. Whether it is a SAM4s, Sharp or Casio you can now create new keyboard overlays with MS Word or Excel whenever you like.
In the good old days your dealer would have a proprietary software and printer that created these keyboard. Believe me because I once paid $1500.00 for a custom software package and plotter to make keyboards and that was when $1500.00 was a lot of money (1985)!
Here are several cash register keyboard templates available for free down load. I always advise people to print a blank one first to test for size, also make sure you printer is not shrinking to fit and almost every register will need legal size paper not letter size!
