[GreenKeys] High Speed Printer

[James M. Walker]

Digital Equipment Corp DEC had several "Page Printers" like that. The
naming of the printers went through several iterations. Started out as
line printers, then went to page printers, and once Band printers. I
think the distinction was a line printer started at the left, printed to
the right then printed back to the left. The page printed a full line at
one time advanced the paper then printed the next line, as did the band
printers. Some folks called the first type Bi-Directional printers.
