## Detailed Description

A PageSetup object stores the page size, orientation and margins.

You can get one of these from the page setup dialog and then pass it to the PrintOperation when printing. The benefit of splitting this out of the PrintSettings is that these affect the actual layout of the page, and thus need to be set long before the user prints.

The margins specified in this object are the "print margins", i.e. the parts of the page that the printer cannot print on. These are different from the layout margins that a word processor uses; they are typically used to determine the minimal size for the layout margins.

To obtain a PageSetup use PageSetup::create() to get the defaults, or use run_page_setup_dialog() to show the page setup dialog and receive the resulting page setup.
