checkpc

Check the printcap database for errors

$ checkpc

$ sudo checkpc -f

$ checkpc -p

$ checkpc -A [7D]

$ checkpc -r -A [7D]

$ checkpc -t [10M]

checkpc [-aflprsV] [-A age] [-D debugflags] [-t size]

checkpc validates the printcap database and printer spool directories for the LPRng print system. It checks file permissions, ownership, and directory structure, reporting problems and optionally fixing them.
The command is useful when installing a new printcap configuration or cleaning up existing printer spoolers. It can identify and remove stale job files and truncate oversized log files.

-a

Do not create accounting files

Fix mode: create missing files and fix permissions. May need multiple runs

Do not create log files

Print verbose printcap information

Remove junk or job files older than age (requires -A)

Do not create filter status files

Report files older than age. Suffix: D (days), H (hours), M (minutes), S (seconds). Default: days

Enable debugging flags

Truncate log files to size in K (kilobytes) or M (megabytes, default)

Print version information

/etc/printcap

Printer capability database that checkpc validates and checks for errors.

The -f option should be run as root. Running as non-root will report many permission failures. Part of LPRng, not CUPS. Systems with both installed may have conflicts.

checkpc is part of LPRng (LPR Next Generation), an enhanced printer spooler system with functionality similar to the original Berkeley LPR software but with additional features and improved security.
