Comment 32 for bug 576491

last night I installed some additional software from hp* here is the list.
A "HP" icon appeared on the notify area. I printed this URL page:
http://start.ubuntu.com/10.04/Google/
and I got the following error:

Thu 13 May 2010 11:24:05 AM CDT
"/usr/lib/cups/filter/hpcups failed"
PAGE: 1 1prnt/backend/hp.c 768: ERROR: cannot open channel PRINT

Here is the list of hp* related packages on my system "dpkg-query -l 'hp*'"
