It's a little more tricky if you're using pdfsharp but quite doable

PdfDocument document = new PdfDocument();
PdfPage page = document.AddPage(); 
XGraphics gfx = XGraphics.FromPdfPage(page); 
XFont font = new XFont("Verdana", 20, XFontStyle.BoldItalic); 
// Draw the text 
gfx.DrawString("Hello, World!", font, XBrushes.Black, 
    new XRect(0, 0, page.Width, page.Height), 
    XStringFormats.Center); 

// real stuff starts here

// current version of pdfsharp doesn't support actions

// so we got to get close to the metal see chapter 12.6.4 of

PdfDictionary dict = new PdfDictionary(document); // 
dict.Elements["/S"] = new PdfName("/JavaScript"); // 
dict.Elements["/JS"] = new PdfString("this.print(true);\r");
document.Internals.AddObject(dict);
document.Internals.Catalog.Elements["/OpenAction"] = 
    PdfInternals.GetReference(dict);
document.Save(Server.MapPath("2.pdf"));
frame1.Attributes["src"] = "2.pdf";
