PrintQueue.CreateXpsDocumentWriter Method (PrintDocumentImageableArea)
Assembly: System.Printing (in system.printing.dll)
public static XpsDocumentWriter CreateXpsDocumentWriter ( ref PrintDocumentImageableArea documentImageableArea )
public static XpsDocumentWriter CreateXpsDocumentWriter ( /** @ref */ PrintDocumentImageableArea documentImageableArea )
A reference to an object that contains the dimensions of the area of the page on which the device can print. Since its data type has no public constructor, this parameter is passed uninitialized.
Return ValueAn XpsDocumentWriter that writes XPS data to a stream. This can be a null reference (Nothing in Visual Basic). See Remarks. (The parameter documentImageableArea is a ref [ByRef in Visual Basic] parameter that is initialized by the method, so it represents a second returned item. See Remarks.)
Many printers need up to a quarter of an inch of unprinted space around the edges of each page to grip the paper and move it through the printer. Otherwise toner would foul the paper flow mechanism. The area which can be printed is the "imageable area."
The type PrintDocumentImageableArea has no public constructor. Hence, the variable documentImageableArea must be declared and assigned to a null reference (Nothing in Visual Basic) and only then passed to the method. This method will display a PrintDialog requiring input from the user. After the user has selected a printer, paper size, and orientation and closed the dialog, documentImageableArea will point to an actual object and its properties will be initialized.
If the user cancels or closes the dialog, the return value will be a null reference (Nothing in Visual Basic). As a consequence, the return value must be checked for a null reference (Nothing in Visual Basic) by your application.
