pprd - PostScript PRinter spooling Daemon
pprd
This command starts the PPR daemon. It is a setuid program owned by ``ppr''.
The first thing this program does is check to see that the real user who
invoked it is ``root'' or ``ppr''. If it is not, then pprd exits immediately.
PPRD uses the directories /usr/ppr, /var/spool/ppr, and /tmp. Its
log is written in /var/spool/ppr/logs/pprd.
PPRD uses the program /usr/ppr/lib/pprdrv to do the actual work of printing
a document. A log of printing done is written in
/var/spool/ppr/logs/printlog if it exists and is writable by the user
``ppr''.
