I had read somewhere that Epson's PictureMate did not work with Tiger, but mine does. I have had my Epson PictureMate for about a year, and I just recently bought a new computer running on Tiger 10.4.2, the printer worked right away, I didn't even have to download a driver, it added itself. I have printed many pictures since then and I have not experienced any problems. I just wanted to get the word out that it DOES work with Tiger, I also read on here that someone was wondering if it did. Hopefully this is helpful to anyone who was wondering about using PictureMate with Tiger.
