Abstract
The LPRng software is an enhanced, extended, and portable
version of the Berkeley LPR software. While providing the same
general functionality, 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;
client programs do not need to run SUID root; greatly enhanced
security checks; and a greatly improved permission and
authorization mechanism.
