Since I code very often little PHP-Scripts which I have to print it would be nice to have a Code-Function that formats the marked area the following:
* Monospace font, e.g. Courier New
* Little, e.g. 10 pt
* Number lines - optional, you should be able to set the startnumber
* syntax highlighting like

* you should be able to choose the language (c++, PHP, Java...)
perhaps you could use the syntax highlighting of kate or gedit
