No, I don't know the actual figures, but the one we had on eval seemed,
subjectively, about 2/3 or maybe 3/4 of that speed. It's an HP, but I
can't remember the model number either. You have to understand that it
was a huge battle getting any scanner at all in our department!

When I worked in CompSci, we got a big fast Oce scanner/copier, about
1997, I think. One of those that collects the output internally,
safely away from fingers, because the paper goes fast enough to cut
fingers off if they're not out of the way. I remember the first print
job I sent it, a large A4 manual printed from a PDF file. I walked the
length of the corridor to the print room, saw no output, and was
slightly surprised -- for about 3 seconds, when a *large* block of
paper was neatly deposited on the output tray.

(Yeah, I must do something about those () keys as well).
