It's actually very, very easy.

Use System.Drawing.Printing.PrintDocument.

Follow the example in that link, or just use the code here (which I excerpted from something doing print automation I'm using every day).

for example, to print off a .jpg (BTW, this won't open any editing application; it spools to the printer in the background)

public void SetupPrintHandler()
{
    PrintDocument printDoc = new PrintDocument();
    printDoc.PrintPage += new PrintPageEventHandler(OnPrintPage);

    printDoc.Print();
}

private void OnPrintPage(object sender, PrintPageEventArgs args)
{
    using (Image image = Image.FromFile(@"C:\file.jpg"))
    {
        Graphics g = args.Graphics;
        g.DrawImage(image, 0, 0);
    }
}
