I just purchased a wide format Epson Stylus Photo 1400 printer. I plugged it in and it installed itself and so far seems to work very well. The only issue I can see so far is that the ink levels are not shown.
I will also have to set up some profiles for printing as the colour is a bit off (does anyone know an easy way to do this?)
Then, just because, I tried to install the printer on my win7 partition. I inserted the cd. clicked a few ok's then tried to print. It asked me if it could download an updated driver. so after a bit and a reboot, I made a print. (and yes it did show me my ink tanks are full)
I compared the two prints from the same file. In Ubuntu I used PhotoPrint (in the repositories) in windows I used Faststone because I used to find it quite good. Now granted I still need to tweak the printer settings in both systems, but the Ubuntu print was head and shoulders better than the windows print.
All in all, this printer works much better in a Linux operating system than it does in Windows7 Ultimate.
The printer does come with a "free" version of photoshop elements, and the print quality may be better from that, but I really don't think it is worth the effort.
To sum it up, kudos to Ubuntu.
