I've been banging my head trying to figure this out and think I may be missing something.
All print jobs seemed to be working correctly but then someone attempted to print multiple copies of a multipage document and it only kicked out one copy.
I read elsewhere that if "collate" is checked as a default on the print server then this can create problems so unchecking it and trying again I WAS able to print uncollated multiple copies of mulipage docs...as long as I don't ever try and collate them. Then it's back to a single printout.
I've switched drivers and the problem persists.
I've attached the printer locally via IP port and I CAN collate jobs with no problem. It only seems to be due to the fact that it's a shared printer.
I've checked user permissions and everything seems ok. Note: I have a networked HP printer that is vending collated...
