Ok so I have an OLD lexmark z600, that's all I know about it, im not tech smart. Anyway i need to print out driving directions by tomorrow for my grandma and i really have no idea how to install it. I have the disk but for some reason when i go to install it, then i go to add printer, the thing where im supposed to click what type of printer it is doesn't have the Z600, but the "lexmark z600" shows up as a selection. So PLEASE, I need step by step DESCRIPTIVE instructions on how to set it up for use.
