I guess, the original 3279 G displays had small (HP?) plotters

Our SAS/MXG performance guy back in the day had a Memorex 3279G
look-alike with its own printer that printed the screen image when the
hardcopy print key on the terminal's keyboard was pressed.
IBM may have had similar hardware, but OEM stuff was cheaper.
We did have a real 3279G which exhibited the "green lightning" while the
LPS (load programmed symbols) data stream was being processed.
