Just to confirm -- Publisher is the only program that crashes when printing? Does Publisher work fine until you try to print?
Interesting -- So, Publisher on that computer will print to other printers fine but when you select the Bizhub, it will freeze? Did it always do this or did it work at one point?
Do you get an error message with the crash?
Are you able to print to that printer from a different program on that computer?
It is very uncommon to have the issue be that specific to a program and printer but works outside of that exact scenario.
Try downloading and installing this HotFix to see if it fixes the issue..

Have you tried removing the fiery driver?
You can download a driver from their own website here: http://www.konicaminolta.eu/en/business-solutions/products/production-printing/discontinued-products/colour/bizhub-press-c6000-c7000-p/downloads.html
I would recommend uninstalling the fiery driver and using the driver from the website above.
