Yes,
this calculator is called the first handheld printing calculator by Texas
Instruments. There are great differenced between the first calculator based on
TI's thermal printer technology - the Canon Pocketronic - and the TI-5050. The
first one used a serial printing method, writing one digit after the other, this
one writes the results in a parallel manner.
The TI-5050 uses internal NiCd batteries to support the printing head with enough power. With the external charger alone you can't get the calculator to work.
The TI-5050 was replaced soon with the TI-5050M sporting an additional memory.
The first really handheld printing calculator was introduced two years later with the TI-5025.
Don't miss the first printing desktop calculator, the TI-500 introduced already in 1974.
