'PrinterSettings object not correctly initialized with disconnected vpn connection

My coworker implemented a function for setting the index of the default printer.

private void SetPrinterToDefault()
{
    PrinterSettings printerSettings = new PrinterSettings();
    int result = 0;
    for (int i = 0; i < System.Drawing.Printing.PrinterSettings.InstalledPrinters.Count; i++)
    {
        if (System.Drawing.Printing.PrinterSettings.InstalledPrinters[i] == printerSettings.PrinterName)
        {
            result = i;
        }
    }
    PrinterIndex = result;
    PrinterSettings.DefaultPageSettings.Landscape = true;
}

For him this function works without problems. For me I get an Exception as soon as the code tries to access a property of the PrinterSettings object.

Exception: hr_error at location 0x000000CFE0976810.

When i inspect the object it shows me the following problem

CanDuplex = Cannot evaluate expression because a native frame is on the top of the call stack.

(German original) CanDuplex = Ausdruck kann nicht evaluiert werden, da sich ein nativer Frame oben auf dem Aufrufstapel befindet.

for all Properties.

What really sucks me up: Every time my PC is connected to our corporate Network via VPN, the PrinterSettings object works as expected.

Any suggestions for a workaround or a solution for fixing the issue?

The solution for me was uninstalling my local WLAN Printer (HP Office Jet 8010). I have no idea why this is working. Eventually the contructor call of PrinterSettings tries to contact the printer, which is in standby and answers to slow.
