Re: Virtual Printers Left Behind

I've had a go at implementing the suggested alternative to WaitForPrintEvent but I'm still seeing instances where the document saved event is not received causing the manual loop to run until timeout (2 mins) before continuing. I have a DbgView log file which I've attached. I also have a dump of the...

Is there some kind of logging I could switch on that would help to identify why pdfsaver6 sometimes fails to produce a document? I really need to get to the bottom of this problem so some kind of response would be appreciated.

The majority of prints are produced at the same speed (10-15 second) but every so often one will take over 40 seconds. The documents that print slowly aren't any larger and it doesn't happen at a set time of day. The customer is just trying to eliminate anything that could slow down the print proces...
