The Lexmark Z602 is a color usb inkjet. Lexmark printers are listed as "almost useless" under linux. However, lexmark ahve been trying to improve. See:
For comment on the Z600 drivers and a url to get them:
You could try installation with one of the other drivers... it may work. If you want to try that, look for a driver that supports something like your Z600: i.e. three color or b&w printing at, what is it, 600dpi? Set up the printer queue as custom on /dev/usb/lp0 (a guess - check yours) and work it from there.
Personally, I'd go for the driver install. No doubt FC3-4 have them in the menue
