[Tinyerp-users] [Patch] Little improvement on printing with the GTK-client

[forum-user]

Linux users who are working with the GTK-client, should first create a preview 
before they can really print. Below you have a piece of code that change that! 

The code first get the installed printers on your system and list them to you 
with the same selectionbox when you click on the action button. Select your 
printer an click on "OK" will send your report directly to your printer.

NOTE: It's only working on Linux! I tested it with Fedora 9 and Ubuntu 8.04.
Change the file <yourclient>/bin/printer/printer.py
