Epson has posted “Public Beta” print drivers for recent Epson Stylus Pro printers to provide full Macintosh 10.5.x (Leopard) compatibility.
These drivers provide enhanced functionality as well as the potential for 16 bit/channel printing–just as soon as imaging applications can actually send 16 bit data. Neither Photoshop CS3 nor Lightroom 1.3 do yet.
The drivers that are currently available are:
Stylus Pro 3800 Series
Stylus Pro 4800 Series
Stylus Pro 4880 Series
Stylus Pro 7800 Series
Stylus Pro 7880 Series
Stylus Pro 9800 Series
Stylus Pro 9880 Series
Stylus Pro 11880 Series
The download page is Professional Imaging Public Beta Leopard Printer Drivers
Additional info is at Epson’s Macintosh Leopard Support
There is no word, at this time, regarding Leopard drivers for Epson Stylus Photo printers such as the R2400 and R1800 although Leopard drivers are expected (some time in December, 2007).
