I thought Centronics dated back to early 1970s - not always in the standard 'modern' form, but in general principles with same signaling and strobing of data.
I got in late. My first encounter with Centronics was TRS80 (1979?)At that time, Centronics did not yet have a monopoly on parallel "protocols", although the company had certainly been around for a while. Once they got the TRS80 market, and then the IBM PC market, any other designs faded away fast.
