Question

I need to get paper size by System.Drawing.Printing.PaperKind. Are there any predefined values? I don’t want to hardcode or calculate paper sizes, I just want to get it programmatically. Thanks.

Answer 1

A subset of predefined values can be had by iterating over a PrinterSettings.PaperSizes collection.

Our application has the user select a printer, providing us with a PrinterSettings object. Contained within PrinterSettings is a list of PaperSize‘s supported by the printer – not everything (note that the XPS Document Driver (win7) supports all sizes).

In our case this subset of supported sizes is all we need. A user specified PaperKind is passed to our printing code, and it goes through our PrinterSettings object until it either finds the user’s selection or gives up and uses a default.

In the example below you can see that the PaperSize objects are correctly filled.

PrinterSettings settings = new PrinterSettings();
foreach (PaperSize size in settings.PaperSizes)
    Debug.WriteLine(size);

It’s only a subset, but maybe that’s also enough for you. the printing APIs in .NET are really unclear and msdn isn’t really much help… Hopefully it puts you on the right track!
