Compare
this calculator with it's direkt predecessor, the TI-5040.
The differences are marginal, instead 10 digits of resolution the TI-5220
displays and prints with 12 digits. Further enhancement is given with the 00-key
to enter hundreds and the GT (grand total) feature.
A desktop calculator with 12 digits capability using normal paper was introduced with the TI-5142 some years later.
Don't miss the really huge TI-5225 introduced in the same year.
Printer paper:
The thermal paper used with this printer (TP-30250 1-1/2" wide and 14 Feet length) was discontinued long time ago. In 2008 Appleton (Appleton, WI) manufactured with the Alpha 700-2.4 paper still a compatible paper.
