We've noticed that scanning is slower on SMP and/or 2.4 than non-SMP 2.2,
but we don't yet know why.

Please look in /var/log/messages.  Do you see messages such as "mlcpp0:
mlcpp_transmit while TX busy"?  This problem has been reported with 2.2.16
and not (yet) with other versions, so it's good to know if this is the same
problem on a different kernel version.

On the other hand, if you are printing while running another application
that uses hpoj, such as SANE or xojpanel, then this is a different known
problem which will be fixed eventually, but for now, the workaround is to
only run one thing at a time.

Which model are you using?  Scanning is not an exact science, and sometimes
color correction is necessary.  xscanimage, xsane, and GIMP all have various
mechanisms for color correction.
