grmedaco,
Did you remove the
Lexmark software, that was installed with the disc, before you downloaded and installed the
Lexmark X5470 Driver?
In HD > Users > Your Account > Library > Preferences: you should also move to the
Trash, any
.plist files, associated with printing or
Lexmark.
In HD > Applications > Utilities: is there no
Printer Setup Utility?
When you installed the
Full Retail Version Of Leopard, did you do an
Erase & Install, an
Archive & Install, or a
Simple Upgrade?
"Mac has no phone support available for me..."
Don't you have
AppleCare?
