Here are the pertinent messages from /var/log/messages when I run the
command "/usr/bin/hp-toolbox" :

Jun 21 11:44:00 dhcppc1 kernel: audit(1150904640.619:12281): avc:
denied  { write } for  pid=2693 comm="python" name="[13078]" dev=pipefs
ino=13078 scontext=system_u:system_r:hplip_t:s0
tcontext=system_u:system_r:hplip_t:s0 tclass=fifo_file

ino=13078 scontext=system_u:system_r:hplip_t:s0
tcontext=system_u:system_r:hplip_t:s0 tclass=fifo_file

Please be kind to me - I know nothing about SELinux.  Though I think I
am about to start learning!  Thanks for the help.
