I notice no difference in time to print on a 586 120MHz box and on a
PII 450MHz box. I haven't benchmarked it, but when you're talking 30
secs per page, if that doesn't make a difference using insane levels
of compiler optimization won't help. :-(
In fact, I have managed to speed things up considerably printing
using the dj550c driver with 3 bits per pixel. Again, this is not a
dramatic increase, but it's better than before.

The uniprint driver tries to provide a configurable interface to the
common functions that printers provide and Ghostscript can use. Sort
of like termcap. Of course a well-tuned C driver will be faster, but
uniprint often can do a very good job because it's smart enough to
optimize some things. And the fact that uniprint has a "capability"
available may clue in a would-be driver author that that is in fact an
efficient way to do things!
I think it grew out of the Epson/stylus drivers, but it does some HP
inkjet printers too now, at least up to the 550/650 level.
