Hi All,
The last problem I reported is fixed now. But SELinux is now preventing
the hp backend from starting. selinux-policy-targeted-3.0.8-8.fc8
I see this in the cups error log...
E [22/Sep/2007:11:20:05 -0700] Unable to
execute /usr/lib/cups/backend/hp: Permission denied
E [22/Sep/2007:11:20:05 -0700] [Job 15] Unable to start backend "hp" -
Permission denied.
And I see this avc messages..
