On Mac OS X 10.7, open System Information (Applications >Adobe flash player for mac os. Utilities) and then under the Hardware section in the left column you will see Printers. Select this and the top right pane will show the print queues on the Mac. Select the printer you want and the bottom right pane will show you information about the printer.

If you had a driver installed previous, did you try to uninstall it with the Fiery uninstall tool? Also, try to download the latest driver from the Fiery website if you not already done so. How do you setup your queue? You do automatically search or do you set the IP address manually (use TCP/IP)? If you already have installed the driver, try to go to cups type in web browser: localhost:631 And you can adjust queue settings in there: make sure it is setup as folowing: lpd://IP_Address/hold you can also use socket://IP_Address:9103 (9100 -print and 9103 - hold) Hopefully this will assist you.
