For many people who had never seen a computer until 1979 (TRS-80),
Centronics printers were the first places that they saw them.
Although business telephone systems had been using them for multi-line
phones for quite a while, "Only technicians" ever connected or
disconnected those.

Might as well ask why ALL D shell connectors are referred to as size B.
