Fired from within the PrintPage event handler of the current print manager, prior to actually printing the page. Allows to adjust the hard margins of the printer (e.g. to compensate for a buggy printer driver, see PrintableArea), or to print the current page in user code (see Handled). See also PrintAsBitmap.

Occurs when an external exception is thrown (e.g. while printing).

Occurs periodically when a long operation is in progress. Can be used to provide progress indication and/or the ability for the user to cancel printing.
