Basically, you can't.

Once the Windows Print Spooler has sent the document to the printer, Windows has no more control or say over the document unless the printer driver provides additional capability to control it. I wouldn't count on having that capability. I haven't found very many printers that provide that capability.

I can trap when the user clicks the Print button on the Print Dialog using the ReportViewer.PrintingBegin but I would like to actually trap it when the printing has finished in order to as if the printing was successful. (I need to tag when an invoice gets printed.)
