I take that back about Versatec, CHM has a document from 1970 on their
electrostatic printer:

I know that Lawrence Livermore had one and used it quite a bit back in
the day.

I worked with one of those on the PLATO system in 1976, where it was used in 
bitmap graphics mode to print music scores.  That at first worked very badly 
because the paper transport was chain driven, with enough slack in the  drive 
that if you'd stop and start it, you'd get irregular paper feeding with as a 
result gaps in the graphics.  I fixed this by writing a new driver that was 
designed to stream, so it would never stop in mid-job.
Interesting.  I maintained a bunch of Versatec 1200A printers at work, and ended up with a couple of them at home.  horrible paper, like a dirty chalkboard, smelly toner, if the paper was handled before it dried the toner could come off on your hands, etc.  But, I had never seen the issue with gaps in graphics, and our drivers, especially on the Nat Semi 16032 system was VERY slow in graphics mode.

When laser printers came out, I was VERRRY glad to move into the future!
