Change printer default paper size

Question

I have several custom paper sizes defined on a printer(the printer is set as default). I need to be able to select one of these formats as the default one.

A program

Answer 1

The following code would set the default printer papersize:

PrintDocument pd = new PrintDocument();
pd.DefaultPageSettings.PaperSize = new System.Drawing.Printing.PaperSize("PaperA4", 840, 1180);
pd.Print();

On how to print using PrintDocument you could refer this link.

Hope this helps.
