The printers for these used a special vacuum tube for memory derived from the kind in television cameras.

They were massive and printed a whole page at a time, similar to the thermal page printers from Perkin-Elmer for their model 3600 Intelligent Terminal of the early 1980's, but P-E printers were much smaller by then.

3600 had vector graphics too, these were very expensive but introduced the form factor of a horizontal box with two 5 1/4 floppies, monitor on top and wired keyboard with the first row of "F" function keys people had seen. Which is the desktop form that was later adopted by IBM when they issued their first PC.
