Free printing software for linux

CUPS provides a portable printing layer for Unix(r)-based operating systems. Common UNIX Printing System has been developed to promote a standard printing solution for all Unix vendors and users.

CUPS provides the System V and Berkeley command line interfaces, and uses the Internet Printing Protocol ("IPP") as the basis for managing print jobs and queues. The Line Printer Daemon (LPD) Server Message Block (SMB), and AppSocket (a.k.a. JetDirect) protocols are also supported with reduced functionality.

CUPS adds network printer browsing and PostScript Printer Description ("PPD") based printing options to support real world printing under UNIX. It includes an image file RIP that supports printing of image files to non-PostScript printers.

A customized version of GNU Ghostscript 7.05 for CUPS called ESP Ghostscript is available separately to support printing of PostScript files within the CUPS driver framework. Sample drivers for Dymo, EPSON, HP, and OKIDATA printers are included that use these filters.

PrintIPP is a PHP class (PHP5) which implements an IPP client (Internet Printing Protocol).
PrintIPP, in its current state, is able to print both strings and files, and cancel jobs, as doing all RFC2911 operations.
PHP PrintIPP project is a Free Software.
PHP PrintIPP is distributed uder LGPL, Http backend under BSD license, testfiles under GPL, test script and examples in documentation under BSD license, documentation under GNU FDL (with no invariant section, no front-cover and no back-cover).
Enhancements:
- There is now an integrated HTTP backend, with Basic and Digest authentication mechanisms.
- Many operations have been added.

CodePrinter is a tiny utility to print out source code or other text files. CodePrinter projects main intent is to provide you with print-outs for your code reviews and to save some paper by fitting two code pages onto one sheet of paper.
CodePrinter is written in Java and makes use of the Java Printing API. Its an Open Source project hosted at SourceForge.net and is protected by the GNU General Public License.
Unix- & Linux people should consider a2ps as an alternative.
Main features:
- Printing of one or multiple files
- Line numbering
- Simple syntax highlighting for .java, .html and .xml files
- Preview with zoom-in/zoom-out functionality
- Printing of a single or all previewed pages
- Font and font size selection

pyWings project allows to consult the Newwings oracle.
Its a completely original modern oracle inspired by the I Ching.
pyWings is written in Python, using the Tkinter interface to the Tk GUI toolkit.
Main features:
- allows saving/restoring of readings for use within pyWings
- simple, highly graphical user interface
- readings may also be saved as text, for subsequent printing or whatever
- formatted hypertext help and information viewer
- pyWings should be portable across X11, Windows 95/98/NT/2000 and MacOS
Enhancements:
- first public release

Gutenprint project, formerly named Gimp-Print, is a suite of printer drivers that may be used with most common UNIX print spooling systems,
including CUPS, lpr, LPRng, or others. These drivers provide high quality printing for UNIX (including Macintosh OS X 10.2, 10.3, and
10.4) and Linux systems that in many cases equal or exceed proprietary vendor-supplied drivers in quality and functionality, and can be used for demanding printing tasks requiring flexibility and high quality. This software package includes an enhanced Print plug-in for the GIMP that replaces the plug-in packaged with the GIMP, and Ghostscript and CUPS drivers, as well as Foomatic data supporting the Ghostscript driver.
Gutenprint has been renamed in order to clearly distinguish it from the GIMP. While this package started out as the original Print plugin for the GIMP, it has expanded into a collection of general purpose printer drivers, and the new, enhanced Print plugin for the GIMP is now only a small part of the package. Furthermore, the name Gutenprint recognizes Johannes Gutenberg, the inventor of the movable type printing press. Finally, the word "guten" means "good" in German.
Gutenprint 5.0.0 is the first stable release of Gutenprint 5.0, and incorporates extensive feedback from the first release candidate. It
is based on the Gimp-Print 4.3 series that has been in development for over three years, and includes many improvements over the very popular 4.2 series.
Gutenprint currently supports over 700 printer models.
Enhancements:
- This release offers support for almost 70 new printers, full support for CUPS 1.2 (including extended attributes and on the fly PPD file generation), corrected support for borderless printing to Epson printers, the ability to choose resizing rather than cropping when printing from CUPS, and more.
- The Mac OS X binary is much faster in some cases on PPC Macs than the initial 5.0 binary.
- All users of Gutenprint 5.0.0 should upgrade.

convert2tifgrayscale is a GIMP plugin that can batch convert to tif grayscale for Offset-Printing.

Converts all images in a specified directory to grayscale, then uses unsharp mask and adjusts levels.

Root-tail is a program that allows printing of text directly to the X11 root window wherever you choose, much like running rxvt with a pixmap background but without the hassle and with more features.
Install:
xmkmf -a
make
make install
make install.man
Enhancements:
- replaced default font by "*" to "ensure" some font is found.
- accept hexadecimal window ids, as does everybody else(?).
- made it compile with ansi-89-based compilers again.
- add hack to support nautilus (not very stable, nautilus should either use extended window manager hints or __SWM_VROOT, as everybody else does).
- do not initialize the window twice (fixes problems with multiple visuals).
- new option: -minspace.
- fixed seg fault if geometry is too short to fit a single line
- fix bug which became apparent if -no-filename or null

Gespinst WebCMS is an easy-to-use Web content management system. It features a file manager designed to be familiar to users of Windows Explorer or GNOMEs Nautilus that is used to work with news, images, calendar events, and users.
A variety of text formatters are provided, including support HTML and Wiki syntax. A forms system is also included for printing, receiving, and validating HTML forms. Additional functionality is provided with optional modules.
Enhancements:
- Fixes a bug relating to a template parameter.
- Adds some functionality for the new module lastcomments.
