The LPRng software is an enhanced, extended,
and portable implementation of the Berkeley LPR
print spooler functionality. While providing
the same interface and meeting RFC1179 requirements,
the implementation is completely new and provides
support for the following features: lightweight
(no databases needed) lpr, lpc, and lprm programs;
dynamic redirection of print queues; automatic
job holding; highly verbose diagnostics; multiple
printers serving a single queue; and a greatly
improved permission and authorization mechanism.

LPRng provides emulation packages for the SVR4 lp
and lpstat programs, eliminating the need for
another print spooler package. These emulation
packages can be modified according to local
requirements to support vintage printing systems.

Attention: Interoperability with older LPD
implementations requires privileged access
to ports. Therefore all affected client-programs
ship with SUID root privileges.
