Hi Don, if you say the delay problem has been solved in CR2008 and your tests prove you right I'm sure it is solved now. We were using CR11R2 for a long time then upgraded to CR2013 for this WPF project. In that project we did not set the NoPrinter option within the reports initially but disconnected Page and Printer Paper sizes (DissociatePageSizeAndPrinterPaperSize).
The reason I mentioned the NoPrinter option is because setting this property to False before changing the PrinterName made the CRforVS viewer print to the assigned printer. Without it the PrinterName assignment is ignored (traced it and the PrinterName stays blank resulting into outputting to the default printer).
I appreciate the attention to the delay problem but that is not the issue here (and probably already solved 
and if not I think the NoPrinter options is an acceptable solution). If you still want an example report I can send you this though.
Best regards,
René
