Vista Tutorial - WPF printing. PrintTicket provider failed.

Hi,

I am trying to print out a WPF window by the following code

PrintDialog printDlg = new System.Windows.Controls.PrintDialog();
if (printDlg.ShowDialog() == true)
{
printDlg.PrintVisual(this, "First WPF Print");
}

and I am getting the following exception on the last line of code

PrintTicket provider failed to retrieve PrintCapabilities. Win32 error:
-2147418113

I am in Vista with HP LaserJet 1012 connected through USB. Application is in
VS 2008, .net 3.5.

What might be the reason for that exception?
