Check out the printcap database
checkpc [ -aflprsV ] [ -Aage[DHMS] ] [ -Ddebugflags ] [ -Pprinter ] [ -t size[kM] ]
Checkpc is used to check for the existence and correct permissions of entries in the printcap database. It is useful when installing a new printcap database and cleaning up existing printer spoolers.
-a
Do not create accounting files (:af).
-f
The fix flag will cause the checkpc program create and fix various files and permissions. It does this in a simple minded manner, and the program may have to be run several times until all permissions are correct. It also reports in extremely verbose details its actions.
-l
Do not create log files (:lf).
-p
Print verbose printcap information. Useful if interested in the printcap values.
-r
remove junk or job files older than the age set by -A. You must set the age to a non-zero value otherwise no files are removed.
-s
Do not create filter status files (:ps).
-A Age[DHMS]
Report junk or job files older than age. The age time can have a suffix days (D) hours (H), minutes (M), or seconds (S); default is days.
-D debugflags
Run the program with debugging flags. See the LPRng HOWTO for details of the flags actions.
-V
Verbose mode.
-P printer
Process only the specified print queue.
-t size[kM]
Truncate log files (:lf) to the specified size in Kbytes or Mbytes (default is Mbytes).
-T serial-line
set process name and start feature test
If the -f(fix) option is specified and you do not run this as root, it will complain, but attempt to carry out the operations. This will lead to a large number of failures reports if the ownership and/or permissions are incorrect.
The files used by LPRng are set by values in the printer configuration file and by configuration options. The following are a commonly used set of default values.
/etc/lprng/lpd.conf LPRng configuration file ${HOME}/.printcap user printer description file /etc/printcap printer description file /etc/lprng/lpd.perms permissions /var/run/lprng/lpd lock file for queue control /var/spool/lpd spool directories /var/spool/lpd/QUEUE/control queue control /var/spool/lpd/QUEUE/log trace or debug log file /var/spool/lpd/QUEUE/acct accounting file /var/spool/lpd/QUEUE/status status file
lpd.conf(5), lpc(8), lpd(8), lpr(1), lpq(1), lprm(1), printcap(5), lpd.perms(5), pr(1), lprng_certs(1), lprng_index_certs(1).

Most of the diagnostics are self explanatory. If you are puzzled over the exact cause of failure, set the debugging level on (-D5) and run again.
The debugging information will help you to pinpoint the exact cause of failure.
