Reply To: PDF to an office printer: colour and greyscale

I'm resurrecting this old thread to post a workaround that a nice person in a printer forum gave me, just in case anyone else has the same problem. If I make a copy of the PDF and use Acrobat to convert it all to greyscale, and then replace the pages to be printed in colour with their counterparts in the colour version of the file, both the black and the colour pages print as they should. (I found and tried the colour management options in Acrobat, but they made no difference.)

It would be nice not to spend time doing that, and there's always the possibility of a mistake with this method, but at least I can now get the printer printing and registering black pages correctly!
