This is bad. Which kernel? I recall older kernels were fubar and they
caused those errors to show up, but that was at 2.6.12 or thereabouts, I
think.

1.3.1.1? Do you have an USB hub in the way? Try connecting the printer
directly to the computer, just in case. Good USB2.0 hubs are hard to come
by.

Looks like the USB issues I recall, alright. It works like this: after you
get the syndrome, you need to remove the uhci/ohci/ehci drivers and reload
them. A reboot does this as a side-effect ;-)
Anyway, if this is a new kernel, I am stumped about what could be wrong
there.

Take a look on /usr/share/cups/models, make sure nothing in there (following
symlinks, even) is not in a loop. I doubt CUPS is smart enough to break
loops, it isn't smart enough for a lot of far more pertinent stuff.
If nothing of the above helps, take it to the HPLIP forum on
hpinkjet.sf.net, HP gives official support there even for tracking down
hardware issues, as long as it is an HPLIP-supported printer (and yours is).
They can't help you with CUPS, but they may be able to help if the usblp
problem shows up again.
