Okay, I changed it from what I read here (specifying a boolean instead
of a string) to get this:
PropertyValue[] printOpts = new PropertyValue[2];
printOpts[0] = new PropertyValue();
printOpts[0].Name = "Name";
printOpts[0].Value = sPrinter;
printOpts[1] = new PropertyValue();
printOpts[1].Name = "Wait";
printOpts[1].Value = new Boolean(true);
I left the print listener in just in case there was a problem and that
caused a problem. I removed the print listener and it worked fine.
Much simpler code and I figure I might save a small amount of time on
each document since I can go on as soon as it finishes, instead of
possibly losing a bit of time sleeping in a loop. While that isn't
much time per document, in some cases my clients are printing hundreds
of documents and the time could add up. Not by much, but it might make
the pages print faster.
