If you need to cancel or disable printing at all you can use the following approach. First, you need to implement a custom print handler. A sample print handler that disables printing is given below.

C#

class SamplePrintHandler : PrintHandler
{
    public PrintStatus OnPrint(PrintJob printJob)
    {
        return PrintStatus.CANCEL;
    }
} 

VB.NET

Class SamplePrintHandler 
    Implements PrintHandler

    Public Function OnPrint(printJob As PrintJob) As PrintStatus Implements PrintHandler.OnPrint
        return PrintStatus.CANCEL
    End Function
End Class

Then, you need to replace current PrintHandler with the new one:

C#

browser.PrintHandler = new SamplePrintHandler(); 

VB.NET

browser.PrintHandler = new SamplePrintHandler()
