Wow, very interesting!  Yup, that's the printer I was remembering.
I never knew there was such a thing as a single line CRT.  And I do remember a good amount of heat associated with that print.
It says shelf life of the paper was 6 months.  That is pretty darn short.

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?
 
What I am familiar with for the storage tube machines used dry silver paper.
It was exposed by a line CRT in the printer then developed with heat.

Earlier 4610. Title is wrong.

They did make a electrostatic one. Never saw it in person. Did use 4610 and
4631 when they were current.

than the aluminum coated paper type previously discussed since it uses toner.
