HP3550 USB Printer and CUPS

Hi folks -

I am having some unexpected trouble setting up an HP3550 USB printer on a box
with fairly current development packages (it is about two weeks out of date
since I could not find any mirror that had a complete set of headers and
files since then).  My parents have ordered the same printer and this Sunday
I planned to hook it up to their similarly configured Fedora laptop and show
them how to use The Gimp enough to print photos.  So today I was hooking up
mine so it would go smoothly at my parents.

The printer is recognized fine by hotplug and the usblp module is inserted and
correctly creates /dev/usb/lp0.  I was able to print the CUPS test page okay
from system-config-printer too.  So I thought I was doing okay.

I noticed in system-config-printer, and in the CUPS administration page, the
printer status is reported as having its media tray empty, when this is not
so.  I saw in the archives a guy with this problem being told it was a fake
error message and could be ignored.

The main problem comes with subsequent attempts to print, basically nothing
happens.  I have been able to cancel print jobs from the CUPS admin webpage,
but I notice processes that seems to be hung lying around, for example right
now in ps -Af:

root      2981  1341  1 18:14 ?        00:00:53 usb:/dev/usb/lp0 85 agreen
(stdin) 1 cpi=12 lpi=7 page-bottom=86 page-left=57 page-right=57 page-top=72
scaling=100 wrap /var/spool/cups/d00085-001

This process seems to be sleeping most all the time, it is not taking any CPU
to speak of.  This hung process seems to then block all other attempts to
print, it does not respond to kill -9 as root, and ignored the job being
cancelled in CUPS.  The first param and the last filepath are referring to
this job being #85, which as far as CUPS is concerned is cancelled.  It was
an attempt to print a jpg in The Gimp.

Does anyone have any advice or suggestions to get further debugging
information?
