We have several iMacs running snow leapord. Each has 8gb ram. FMServer 11 is running on a windows server 2008 r2.

The iMac users are using FMPro ver. 11.

Each time they print, filemaker crashes when finished. If they try to print to the network printer or print to a pdf, it crashes.

Any suggestions?

When you say it crashes, you mean FileMaker application crashes?  If so, does it provide any type of error message?

 

Have you checked if the printer drivers are up to date and test if users can successfully print to those printers using other applications?

 

I'd also try uninstalled printer drivers and reinstalling them on a client machine to see if it fixes the issue.
