Additional Information
The older SDK MapView.Print(printerSettings) function was marked obsolete and was replaced by a new MapView.Print(printerSettingInfo) or Layout.Print(printerSettingInfo, MapSeriesOptions) function. Here are some snippets: PrinterSettingsInfo info = new PrinterSettingsInfo(); var printerSettings = info.PrinterSettings; printerSettings.PrinterName = "some printer name"; printerSettings.DefaultPageSettings.Landscape = false; printerSettings.Copies = 1; info.DoShowSelectionSymbology = false; info.LayoutOrMapName = layout.Name; layout.Print(info);Workaround
Use the new Pro 3.5 MapView.Print(printerSettingInfo) or Layout.Print(printerSettingInfo, MapSeriesOptions) functions.
