They come in the install package - either download or CD/DVD - when you buy the printer.
Looking for mac 10.5.1 install download. Do you know what it's called? It's not the "driver" is it? I have the cd but was hoping to install the most current. I did install 6.10 from the UK site, but I inadvertently "nuked" the Pro38... profiles.
Edit: Fixed. Re-installed the driver. Thanks again.
