As a start you might try:

# setsebool -P cupsd_disable_trans 1

This would turn off SELinux protection for the cups daemon, whilst 
leaving you able to have SELinux turned on for everything else.

An alternative that might be worth trying would be to change the context 
of any directories you want cups to be able to write to, something like:

# chcon -t print_spool_t $HOME/cups-pdf-doc

Not sure if that'll work though.
