I agree on Tektronix. When I was at UMASS in the 70's, we had a printer on the Tektronix 4012 that had some strange paper like that. White crystals grew on the case where the paper came out - kind of strange, I wonder what the technology was??

I concur. Tektronix also made electrostatic printers; this

description matches the paper they use.

Sounds like electrostatic paper, like the kind used in the Radio Shack

screen printer for the original TRS-80.

If I recall the process, the printer has pins that create a small spark on

the paper surface which makes a black mark as the printed element. Most

likely in a dot-matrix configuration. Others may have more detail and

corrections to my explanation.

I have some rolls of paper with only a generic part number.

8" wide, like a teletype roll

but silver/grey metallic coating.

I don't think it's thermal.

What printer technology used that?
