When I try to print anything out, I get no printout. Even a test
page does not come out.
But no indication of trouble shows up on the monitor, and no indication of trouble on
the
printer's display. I did download and install the driver. cups gives no hint of
trouble that I
recognize. If I restart the system and boot up with Windows 7 home, I do get printouts.
The printer is a Xerox WorkCentre 6015ni, I'm using Fedora-18, 64-bit, and the
printer is
connected to the system via usb bus. This is a stand-alone home desktop.
I'm neither trained nor experienced in sys. admin. I've exhausted the help I can
get from
the printer's manual (media and web site). Any help you can give will be
appreciated.
The first specific "symptom" was this in "/var/log/messages":
May 13 16:26:13 c-69-138-198-76 colord: Device added: cups-Xerox_WorkCentre_6015NI
May 13 16:26:14 c-69-138-198-76 cupsd[625]: p11-kit: couldn't open config file:
/root/.pkcs11/pkcs11.conf: Permission denied
This was solved by changing the permissions for "/root/" to 770 (drwxrwx---).
From this point on, Ed Greshko worked with me off-line to solve this. The next symptom to
appear was in "var/log/cups/errorD [21/May/2013:18:24:12 -0400] [Job 21]
Xerox_WorkCentre_6015NI: error while loading shared libraries: libcups.so.2: cannot open

One probable cause was that I (probably, I don't clearly remember) used
"rpm" rather than "yum" to install Xerox's driver. Another part
of the problem was that Xerox's driver used 32-bit libraries, and my system is a
64-bit system. This was fixed by installing the 32-bit library for
"libcups.so.2":
"yum install cups-libs*i686"
I still couldn't print. But I noticed alerts from SELinux. The SELinux Alert Browser
said:
SELinux has detected a problem.
The source process: xrhk2ap
Attempted this access: execmod
On this file: /usr/lib/xrhk1acl.so
The SETroubleshoot Details Window said:
SELinux is preventing xrhk2ap from execmod access on the file /usr/lib/xrhk1acl.so.
***** Plugin allow_execmod (91.4 confidence) suggests **********************
If you want to allow xrhk2ap to have execmod access on the xrhk1acl.so file
Then you need to change the label on '/usr/lib/xrhk1acl.so'
Do
# semanage fcontext -a -t textrel_shlib_t '/usr/lib/xrhk1acl.so'
# restorecon -v '/usr/lib/xrhk1acl.so'
[... snip ...]
This was fixed by entering the two suggested commands:
semanage fcontext -a -t textrel_shlib_t '/usr/lib/xrhk1acl.so'
restorecon -v '/usr/lib/xrhk1acl.so'
This fixed the problem. I was then able to print.
