We have serveral problems while reading the Printersettings received from the 
PrintPageEvent.

* The PageSettings are invalid when you use a HP Plotter and a custom page 
size .
* The PageSettings are invalid when you use a PostScript Printer and a 
custom page size
* If the printer is the default printer, access the page settings is slower 
(differences between drivers are very big).

Simple test is to install a PDF printer, and use the PrintDocument to Print 
300 empty pages, and every time print a page access the Margins and do 
anyhing with them.
