Might check with ABDick for help. They have support documents.

What sort of problems?  Back when we had an older level 2 rip, when I dealt
with Publisher files  I would make a SEPARATED (not composite) PDF, use
Pitstop to convert the PDF to grayscale (because the separations will be RGB
gray from Publisher), do any required impositions using Quite Imposing and
then print the PDF to my platemaker.  Convoluted but it usually worked
better than printing directly from Publisher to the old rip.  Now that we
have a new rip printing separations directly from Publisher to the rip works
fine.  In fact handling Publisher files was one of the big reasons behind
upgrading our rip - our largest customer utilizes Publisher and we were in
danger of losing the account due to printing problems with Publisher and the
old rip.
