I have several Windows 7 x64 bit computers setup in the office. I have downloaded all the latest drivers from the manufacturers. I have installed these printers on each workstation as a local printer via IP port. Each workstation prints just fine, however I cannot get any of them to collate multiple copies. I've tried setting the defaults to collate, no go. No matter what or how I am certain I have the preferences set to collate (i.e. FirstPage SecondPage, FirstPage SecondPage), it still groups the print outs. (i.e. FirstPage, FirstPage, SecondPage SecondPage and so on) This is quite a problem on 500 page reports.
