How to print In Linux?

On UNIX/Linux systems you have the choice, which software you like to use to print out your documents. Four programs are introduced now, which you can take to use CUPS quite comfortably.

You have to decide which of it fits best to you and your purposes. 

Xpp

XPP is a little print panel for the X Window system that gives you the opportunity to use all the features of your printer very comfortably as long as they are supported by CUPS.
It can be downloaded at

http://cups.sourceforge.net/xpp
In order to use XPP from a given application you just have to use the xpp instead of the lpr/lpd command. Just type in xpp and you can choose a printer and its options.
