                htmlPrinter.PrintToNonDefaultPrinter(// this methods is in another project to print html
                     printerName: objScreenLabel.PrinterName,
                     html: PrintLabel,
                     title: "demo print to non default printer",
                     copies: 1,
                     papername: objScreenLabel.pageName,
                     pageheight: objScreenLabel.pageHeight,
                     pagewidth: objScreenLabel.pageWidth,
                      layout: objScreenLabel.layout
                   );
                System.Windows.Forms.Application.Run();
			}
            catch (Exception ex) { }
		}

It is working fine when application run at visual studio. When we make the installer of this windows service and call this method every goes smoothly we can't get any error but html is not printing .

Please anyone help to solve this problem.

Thanx

Looks like you're trying to display UI from a Windows Service. Windows Services are not interactive processes. You cannot show UI from a Windows Service.
