Lout is a document formatting system which reads a high-level description of a document similar in style to LaTeX and produces a PostScript file which can be printed on most laser printers and graphic display devices. Plain text and PDF output are also available. Lout is inherently multilingual and adding new languages is easy.
The rlpr package makes it possible (or at the very least, easier) to print files on remote sites to your local printer. It includes BSD-compatible replacements for `lpr', `lpq', and `lprm', whose functionality is a superset of their BSD counterparts. In other words, with the rlpr package, you can do everything you could do with the BSD printing commands, and more. The programs are all smaller, cleaner, and more portable than their BSD equivalents, and supported on just about any POSIX.1 system.
npadmin is a command line tool to administer network printers. It is based on the concepts of JetAdmin and other vendor's tools but is designed to be scriptable. It uses SNMP to query the common printer MIB (RFC 1759) and return information about the printer. There is a surprising amount of information available in the common printer MIB and since the vendors all use their private MIBs, this appears to be the only tool that makes it available.
LPRng is the Next Generation in LPR software. It supports the standard bsd lpr commands and also supports an System V interface. Other features include lightweight 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 default configuration provides a simple BSD LPR interface, but there are options to modify a wide variety of operational facilities. The companion IFHP print filter can interface to a wide variety of printers, from the latest network based high speed to vintage legacy printers.
Apsfilter is a magic printfilter, allowing you to print different document types "automagically" without having to convert them manually into something which is understood by your printer. Apsfilter is a mature and powerful printing solution for any flavor of Unix running lpd or LPRng. It supports the latest GhostScript version and 3rd-party printer drivers (such as hpijs, ijs, hpdj, pcl3, and gimp-print). It autodetects lots of file, archive, and compression types. It supports printing on local as well as on Appletalk, Unix, and Windows remote printers. General and "per printer-queue" based config files allow you to configure the printer for your needs. The lpr command line options allow you to change printing parameters like print quality, orientation, duplex mode, etc. "on the fly" without having to edit any config file. A SETUP script helps you to test various supported ghostscript drivers prior installation, makes the necessary entries in /etc/printcap, creates spool directories, and creates apsfilter default config files as needed. A handbook in HTML is available. Several tools are also included: "aps2file" allows you to print to a file via apsfilter, "apspreview" previews files as generated by apsfilter using gv and friends, and "apsfilter-bug" assists you in doing bug and problem reports.
TransFig is a set of tools for creating TeX documents with graphics which are portable, in the sense that they can be printed in a wide variety of environments. The fig2dev program that is part of TransFig is used by xfig when exporting drawings to the various output formats such as PostScript (and EPS), CGM, JPEG, LaTeX, PNG, and more.
PPR is a Unix print spooler expressly designed for operating PostScript printers. Its features are numerous, and it supports printers connected to parallel or serial ports, or over the network through AppleTalk, LanManager, LPD, and TCP/IP protocols. It accepts jobs from Microsoft Windows, Macintosh, and Unix clients. If the input file is not PostScript, it can pipe the input through a filter. PPR has been designed to manage large numbers of printers with minimal operator attention. It has command line and Web interfaces.
