Our purchasing dept then thought to have made the savings
of the year when they acquired a bunch of HP 5s instead of
the recommended 4s. After a week, it was found out in the
offices that this printer had trouble with large files.

Though that could be an uncorrectable firmware problem, it might also be
that they don't have enough memory. Can you add more?

I had opposed the purchase of HP5, because that one appeared
to me as a home use device rather than for heavy office use, but
reason could not compete with the possible savings.
Then I just had PC Mag in front of me where the flaw was reported,
when a mate entered "Hey, my printer doesn't print." Whereupon
we proved, that the report in PC Mag was correct, indeed :-).
About ten or so years ago. Sorry, don't rermember more. Ours
were probably dumped.
