and to the original poster, your output shows owner root
on the cups admin page you can set up your "allowed users"
also you can edit your config file and change to debug instead of (probably) warn mode
grab the log out output and in a text editor remove any sensitive info like your name and email address etc
upload it and link us to it pls
I like dropbox for that, rename the log to cups.txt will allow us to see in in the web browser
2) how did you install this printer as there are about 3 ways
1) create root password
b) go to localhost:631 with printer turned on
c) click add printer to get root login dialog box---this must be done as config files are owned by root
d) then click again and choose find new printer if not yet found
e) choose make model or manaully choose hp then pull down make and model
f) set up default options including if its shared and who can use it
############## or
############ or assuming its kept the mandriva type control panel
go thru to the control panel to add printer
