According to the docs ReportProcessor.PrintReport Method (ReportSource, PrinterSettings) API | Telerik Reporting the function reportProcessor.PrintRepor shoul accept null as a second paramenter in order to open the system dialog window, however, in reality this function requires a second parameter of type System.Drawing.Printing.PrinterSettings so null is not an option.
The thing is I want to prompt the user to select the printer they want to print to.
I´m using Asp.net core 6 MVC, with C#.
For web applications, in order to start the print with the dialog, you may use the HTML5 Report Viewer and its print command, for example:
$('#printButton').click(function () { var rv = $("#reportViewer1").data("telerik_ReportViewer"); rv.commands.print.exec(); });
