Recently i bought a printer from Dell with the idea to use it with all pc's and mac's in the house. It has a wifi module so u can access the printer over the network. Unfortunatly seems that dell doesn't support Mac's

After lots of researches i found out that the printer is in fact Lexmark X7170 and the wifi adaptor too. The lexmark printer HAS drivers for linux , mac, dos...all. I've tryed to install them on my wife;s iMac and seems that the drivers looks for lexmark strings so, it will not work with my dell printer. If anyone can help me I'll realy apreciate it.
Also i managed to put my hand on firmware for the printer but seems in the printer is stored a serial number from which the firmware deceide if to show Lexmark or Dell.
