The street fighter sleeve shown above was printed on an HP Photosmart C4385. It's discontinued but you can buy the c4400 series that replaces it. Same ink, same resolution printing, same price. $99. It's also wireless. I recommend printing with the photo cartridge installed instead of the black so that you get the added benefit of of Cyan and Magenta. This will make a cover print that looks better than a standard sleeve (i believe this). Also, I like to scale all the covers up to 1200dpi before I print. This interpolates the image and gives a smooth look. Then I print at 1200dpi.
