>I'm writing a document printing system that prints documents in PDF form using ShellExecute (From Message 130310) . I need to be able to specify the number of copies to print. I could do a FOR loop, but that creates one job per copy and I was hoping to to specify the copies and print. I've also looked at doing Acrobat Automation, and from what I can tell you can't print via automation at all. Is there a way to set copies via ShellExecute?

May be you can adjust Printer Job directly using WMI? Not sure, if this is possible, though.

Check this Enumerating Jobs in Print Queue as a starting point.
