What it is

The Seiko Epson TP-80 is an eighty-column dot matrix printer.[1]

The TP-80 was released to the market in June 1978.[1]

The TP-80 was mainly used as a system printer for the Commodore PET computer.[1]

How it works

General reference — not yet source-verified

Dot matrix printers form characters and graphics by striking an ink-soaked ribbon against the paper with a set of pins arranged in a print head.

The print head moves horizontally across the page, and the pins are fired selectively to create patterns of dots.

Where it fits in the process flow

General reference — not yet source-verified

Dot matrix printers were typically connected to a host computer as a peripheral output device.

In a computing workflow, the printer receives text or graphics data from the computer and produces a hard-copy output on continuous-form paper.

Applications

The TP-80 was employed as a system printer for the Commodore PET computer, providing printed output for home and business applications.[1]
