Print UI hangs on launch and will not close

[GNAServicesInc]

If I launch the print UI from the system control panel it takes forever to open (if it opens) and when it opens it will not close and then will crash.

If I try to print from an application the print everything locks up and eventually goes back to normal but no print UI is shown.

Not sure if this is the cause but I noticed the report states.

exit code 2: grep: /etc/cups/ppd/PDF.ppd: Permission denied

So that is 0640 but the documentation on http://www.cups-pdf.de says it should be 0700.

<a href="http://www.cups-pdf.de/documentation.shtml">CUPS-PDF requires root privileges since it has to modify file ownerships. In order to ensure CUPS-PDF is running with the required root privileges you have to make 'root' the owner of the cups-pdf backend and set the file permissions of the backend to 0700 (root only)</a>

Another thing I have noticed, again not sure if related but none the less here it is.

I am unable to remove the package printer-driver-cups-pdf (I assume this package is related as it is the only 'pdf' cups package I see installed.

If I try to uninstall it the system just hangs up and dose not nothing, frozen on uninstalling.

Also, do you think this is related to bug 562679 ?

Hello GNA,
Thank you for submitting this bug and reporting a problem with the system-config-printer package. You made this bug report in 2015 and Ubuntu and the system-config-printer package have been updated since then.

Could you confirm that this is no longer a problem and that we can close the ticket?
If it is still a problem, are you still interested in finding a solution to this bug?
If you are, could you let us know and, in the current version, could you run the following (only once):
apport-collect 1479143
and upload the updated logs and and any other logs that are relevant for this particular issue.

Thank you again for helping make Ubuntu better.
