The Windows "spooler" service in your NPrinting environment has been disabled. Doing so causes NPrinting report execution to fail with a similar error below in the NPrinting Engine log:

 

 

Qlik.NPrinting.Engine 21.0.0.0 Qlik.NPrinting.Engine.Consumer.ContentResolver 20210804T142254.673+02:00 WARN SPCH1125 0 0 0 0 0 0 0 0 Navigator stuck or died on connection at Tracker.PDFXChange.IPXCControlEx.get_Printer(String pServerName, String pPrinterName, String pRegKey, String pDevCode)↓↓ at Qlik.Reporting.Printers.QlikPdfPrinter.Win64PrinterFactory.get_Item(String pServerName, String pPrinterName, String pRegKey, String pDevCode)↓↓ at Qlik.Reporting.Printers.QlikPdfPrinter..ctor()↓↓ at Engine.Navigator.QlikView.QV.Resolvers.Contents.SomethingReportNodeRequestResolver`1.PerformPrintWork(QlikViewDocument doc, Dictionary`2 settings, Int32 dpi, Action`1 doPrint, String fileName)
