LPRng: RESOURCES – PostScript, Epson, HP, Xerox, PPD, etc

Posted by jpluimers on 2022/09/28

When writing Some links on PostScript books and online content, back from the days, I archived [Wayback] Index of /RESOURCES from the site hosting the [Wayback/] LPRng Web Page (see also LPRng on Wikipedia):

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; client programs do not need to run SUID root; greatly enhanced security checks; 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.

Subdirectories (the PPD one goes one level deeper with both files and directories; XEROX just has a subdirectory with one file):
