Auto-Print

[mportnoy]

I am using the auto-print sample as the basis for batch converting 1000s of RTF files. I am curious as to what performance gains I will see if create multiple instances of the print driver and simultaneously convert. For instance, I could create 2 instances of the print driver and simultaneously convert 500 at a time using each driver.

What type of performance gains should I expect?
Do you have any recommended techniques for such an example?
Is it possible to use the AutoPrint DLL in such a way that I queue multiple documents and then convert at once or must I call BIAP's Initialze / StartPriting / Stop Printing in sequence each time?
