Free pretty printing software for linux

Pretty Code Web is a syntax highlighter for publishing code, written in any programming language, to the web.
Written in php it uses syntax files separate from the main code to highlight a specified language.
Main features:
- Syntax highlighting for (potentially) any language.
- User defined syntax files.
- User defined colors
- Separate colors for:
- 6 Keyword Groups
- Text Strings
- Operators
- Block and Line Comments
- Bracket Characters

PackPrint provides a pretty-printer for ethernet packets.
PackPrint is a program to parse and print out ethernet frames in a pretty way. For protocols that it knows about (ARP, UDP, TCP, ICMP, and raw IP), it will decode the data and print it out in an easy-to-read format.
Main features:
- PackPrint will display the contents of ethernet frames. For protocols that it knows about, it will decode the data and print it out in an easy to read format
- The protocols that PackPrint currently understands include
- ARP
- UDP
- TCP
- ICMP
- IP
Usage:
PackPrint is incredibly easy to use - simply to packprint , where is the name of a file generated using the -w option for tcpdump (or some other program using libpcap).
If is -, then packprint reads from standard input, so you could do:
$ tcpdump -s 65535 -w - | packprint -
to produce an nice output for tcpdump
NOTE: always use the -s 65535 options on tcpdump to make sure you get the entire packet contents so that packprint can decode it

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.

FSP Client is single executable client for the FSP protocol. Client uses an FTP-like user interface. People usually find this program easier to use that multiple client programs in FSP protocol suite. If you are at least somewhat familiar with command line FTP and want to try FSP, this program is a good choice for you.
There is a help command; not a very good one, but it does tell you the commands. Type `help to get a list of all commands; to get a brief description of a command, type `help name (`name being the command); to get brief help on all commands type `help all (warning: there are 46 commands).
See the manual page fsp(1) for a somewhat longer description...
Note for versions since 0.0-g: the command `cat, `get, `du, and `tar can all take a `-r flag -- this causes the commands to process subdirectories as well as files. e.g., `du will give the disk usage of the current directory; `du -r will give the disk usage of the current directory and _all_ subdirectories (resursively). The `timeout command causes communications to return an error code if the timeout occurs; this means that:
timeout 30
pro
iferror exit
is a good way of determining whether a remote site is alive or not when writing scripts. The `ver should only return an error if the timeout occurs -- however, pre-2.6.3 servers return version strings as an error which messes up that usage...
Macros are, for want of a better word, stupid. Until parameter variables are allowed, they can not do very much. Common ones (and user set up options) should be defined in the file ~/.fsprc (i.e., .fsprc in your home directory). This filename can be changed by setting the environment variable FSPRC. An example .fsprc is supplied in the file `fsprc in this directory.
It is also now possible to have commands like:
ls -l | less
Anything after the first `| symbol is fed the output of the builtin command...
rehash may need a little explanation -- when you do an ls, the directory information is fetched to the local end and stays there (thanks to the original authors stuff); if you want to check if anything has been updated since you did an ls of a directory, then you must rehash first. The client is now a bit more intelligent than it used to be (i.e., pre `d release); it will automatically mark directories as out-of-date if it knows that it has modified them (e.g., by put, or mkdir or whatever). Its the wrong command name, but it brings back fond memories of csh... It may sound like a disadvantage -- in fact it is an enormous benefit having it work this way... *much* faster.
All the commands which have a f equivalent in the original distribution behave as before; well, pretty much.
Oh, one last thing -- command lines cant have continuations... yet.
-------------------------------------------------------------------------------
If you use it and like it, mail me. I need the encouragement If you use it and dont like it, mail me. I need bringing back down to earth...
Basically, even though it is pre-alpha, I would still like to know whether people like it or not... just dont complain too loud when it doesnt work right :-)
Enhancements:
- fsprc: wrack removed, decss added
- fixed statistics printing in stat command
- client/util.c add static prototype declaration
- avoid hammering of down sites
- fsprc: another FSP site added

Pebrot is a text MSN messenger client implemented with Python. It has also a pretty and colorful Curses-based interface. It is developed to work under Linux and should work fine on any other *nixes.

RepTool is a reporting/printing tool.

RepTool is composed by two components: libreptool, which manages source files that are the reports definition, and it produces the report/print; greptool, which visually creates reports definition files.

GNU enscript converts ASCII files to PostScript and stores generated output to a file or sends it directly to the printer. GNU enscript includes features for "pretty-printing" (language sensitive code highlighting) in several programming languages.

It supports ten different input encodings, Adobe Font Metrics files, and user defined fancy headers. AFM files for the most common PostScript fonts are included in the distribution; the program itself can download PostScript fonts.

Other features include language sensitive highlighting, N-up printing, inlined EPS images, comments, and the ability to change body color and font on the fly.

- ISO-8859-1 ISO Latin1 (default)
