LPRng-HOWTO
13 Apr 2000 (For LPRng-3.6.14beta25)
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
independent 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 SETUID root; greatly enhanced
security checks; load balancing across multiple printers;
and a greatly improved permission and authorization mechanism.
The source software compiles and runs on a wide variety of UNIX systems,
and is compatible with other print spoolers and network printers that use
the LPR interface and meet RFC1179 requirements.
The companion ifhp print filter is used with the LPRng to provide
hardware level support for PostScript, PCL, text, and other printers.
The ifhp filter also provides diagnostic and error information as well as
accounting information.
The LPRng distribution also has a set of easily customizable programs to
produce banner pages for job identification.
The SVR4 lp and lpstat functionality is provided by a set of emulator
programs,
and LPRng can be easily integrated with the Samba SMB support package.
For users that require secure and/or authenticated printing support,
LPRng supports Kerberos 5,
MIT Kerberos 4 extensions to LPR,
PGP,
and simple MD5 based authentication.
Additional authentication support is extremely simple to add.
