UDP Broadcast blocking question

I have a very unique networking question. And I'm not sure where to ask it. So I'm asking in the general networking section. If it needs to be moved to make more sense I'm fine with that.

My question is as follows. I have a Xerox Phaser 8560MFP printer on my network. These printers are designed to shutdown if they see anything on the network that might "harm" them. The printer will also not startup properly if during startup it senses an issue on the network.

This printer was working fine, until an update to a piece of software I use was made. And I have fully diagnosed the issue down to if this software is not running the printer stays on the network and works fine. But as soon as the software starts up the printer shuts down.

The change to the software was that it now does a constant UDP broadcast. This was the only change that we can detremine in the software would have the potential to affect the printer. the UDP broadcast is not on the standard port 9100 that Xerox printers use. So it isn't a port conflict.

Does anyone know if there is a way with a switch, router, or firewall software on the computer that I can block this UDP broadcast from printers IP address? Both the computer and printer have static ip addresses, so being able to configure something for them should be doable. Just not sure what I can configure to block it. I have an email out to the xerox tech's to see if there is a way to tell the printer to ignore this broadcast, but if theres a way I can do it that would probably be better then changing something on the printer.

Some more information that might help.
Computer is a Mac OS X snow leopard machine.
router is a linksys e3200
switch is a cisco smart switch, i forget the model number i'm not at he location to look at it at the moment.

Any help or advice would be greatly appreciated.
Thanks
