It took a long time between the first calculator based on TI's thermal printer technology - the Canon Pocketronic - and this universal printing desktop calculator. Introduced 1976 it features both a 10 digit flourescent display and a quiet, convenient thermal printer. Together with a 4-key memory this calculator defined the standard in its class.
This calculator was a great success for Texas Instruments, it was produced more than 5 years before the TI-5142 was introduced. Later models like the TI-5040 II or the TI-5130 had shorter life cycles.
The style of the keyboard and some design elements of the TI-5040 were adopted both by non-printing calculators like the TI-5100 and print-only calculators like the TI-5015.
The TI-5220 printing desktop calculator with similiar specifications but sporting a 12 digits display was introduced in 1977 together with its huge sibbling TI-5225. Don't miss the TI-5135 introduced in 1980.
The first portable printing calculator TI-5050 appeared one year earlier on the market.
Even Texas Instruments never mentioned the rare TI-500, a printing calculator introduced already in 1974.
The thermal paper used with this printer (TP-30250 2-1/2" wide and 14 Feet length) was discontinued long time ago. In 2008 Appleton (Appleton, WI) manufactured with the Alpha 800-2.4 paper still a compatible paper.
Offers the best of two worlds. An easy-to-read display. A printed tape.
