Did this ever work the way you expect it to?
Did you find any help at the Lexmark site (I know...this is a long shot 😉
Please accept my heartfelt apologies for the problems you are experiencing with your Lexmark product. To the best of my knowledge, there are currently no plans to develop Mac OS 10.4(tiger) drivers to support this model. Thank you for notifying us of this request. I will forward your comments on to our development department, as it is only through input from you, our customers, that we can make these important business decisions. However, you may try driver for OS X 2.4 which may work for Tiger OS X 4.1 too, although it is necessary to download after (OS X 4.1) installation.
