Hi,
I tried what you have suggested and encountered the following problems.
Firstly, when I dragged the clean up tool into Terminal, it did not request my admin password, and it appeared that all the cleanup tools attempts to remove the files were rejected as at the end of each line it simply said "permission denied"
So, I searched for all the lexmark files manually, selected everything and deleted them
I then went back through the whole installation process, and the printer will work with a USB, but won't work wirelessly, so I'm no further forward.
It shows the green light after completing the wireless set up, but when you disconnect the usb, and attempt to print, the printer programme shows that the printer is "offline" and can't commuincate with it, even though the wirelss light is showing green.
I also get a message to say that I need to download further software when I plug the printer in, so go through the apple update, which results in nothing, and "contact the manufacturer"
As I said, the printer will work on a usb, but its a wireless, and I was hoping to work it wirelessly.
Are there any other suggestions???
