Epson's Stylus Pro 4000 is not supported with 10.5 but will print on simple sheets. It does not have the roll paper options. Frustrating, since Illustrator CS3 has said problems with color accuracy with custom profiles were a printer driver problem. New OS, but even the old driver does not work properly. If anybody knows a work around PLEASE post it. I tried installing the old driver. That did not bring back full control. Otherwise, EPSON Pro printer users beware.
