Great!!!
Lost my long post!
There are still some bad bugs on this site.
Anyway, here what I actually wanted to post:
It surely has something to do with the drivers. And deleting the driver and setting it up again (the way you did) is not a clear reinstall. You need to delete some more files in different folders, which I can't recall yet.
Anyway, I got the idea that you should try to access your printer over TCP/IP and turn off appletalk. How to do? You need to turn off appletalk on the printer menu. Then set up a new printer using TCPI/IP instead of appletalk. You will need to specify the ip of your printer, since it's running as a printserver.
Why this idea? Maybe the drivers for your lexmark printer have some probs with panthers appletalk?!?
I had another idea too:
is it possible for you to plug the printer directly to your mac? Using usb... It would be great for testing.
Ok, sorry for this briefly post, but I am really pissed that I lost the one I wrote before. Next time I will copy my text before I send it. Grrrrr
