PrintUnixDialog and mono

I'm new to Mono and I do not understand how the PrintUnixDialog and the PageSetu开发者_运维知识库pUnixDialog work

I have searched it on google for hours but I haven't found anything

So if you know a good tutorial please post the link, or if you have a working sample, that would be good too.

I hope my english is not too bad, so Thanks in advance
