[ale] Fedora 11 update broke my printer

[skotchman at gmail.com (Scott Castaline)]

Yesterday all the hp related files were updated on F11. My printer 
started reacting strange last night in that certain files would not get 
printed, but would sit in queue "processing" indefinitely. This morning 
when I booted it just stopped working period. I now get 
/usr/lib/cups/backend/hp failed. I have tried to downgrade in yum and 
that failed. Tried cleanup of hp packages and that failed. All my 
searching only turns up this problem with USB printers, mine is network 
connected. Through the HP GUI Device Manager I am able to print the 
"Print Quality Diagnostics Page", that's it. If I do the following, 
"lpadmin -p `HP Officejet Pro l7700` -E -v
hp:/net/Officejet_Pro_L7700?ip=xxx.xxx.xxx.xxx" I get -bash: HP: command 
not found. I am doing this su'd to root. From the CLI I have not been 
able to get the correct URI all I've been able to get is "direct hp".

When I try to execute /usr/lib/cups/backend/hp I'll get, "direct hp 
"Unknown" "HP Printer (HPLIP)"". My thinking is that the update 
clobbered something to do with the printer config. Should I attempt to 
delete the printer(s) and then recreate them, or is there something else 
that I can try?

TIA
