When I run application on server, it prints locally via StimulSoft Print Method to a Physical thermal Printer Properly, but when I call same method from a client app from WCF, get this error:

"Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application."

PrinterSettings ps1 = new PrinterSettings();
ps1.PrinterName = MyPrintControler.SellerPrinterName;
stiReport.Print(false, ps1);

  • If you're running that website on IIS, try `sc config w3svc type=own type=interact` or configure the service process on the server to ["interact with the desktop"](https://stackoverflow.com/questions/4237225/allow-service-to-interact-with-desktop-in-windows) and see if that solves your immediate problem. – rene May 18 '19 at 12:14
  • Problem Solved, when i used print method with 2 parameter, not with 1 parameter!!!! – nima khankhanizadeh May 18 '19 at 19:18
