The Phaser 3100 is a GDI printer. The Gutenprint drivers do not support such printers.
You should be able to print with the Xerox drivers provided for OS X 10.4. To make the drivers work in OS X 10.6, install the drivers from Xerox. Then in a Terminal window (/Applications/Terminal) run the following commands--
sudo chown -R root:admin /Library/Printers/Xerox/
sudo chmod 775 /Library/Printers/Xerox/filter/rastertoprinter
You will have to force any 64 bit applications to run in 32 bit mode to get the full functionality for the drivers.
