Summary: The cartridge leaked ink along the side of each page even when I was only trying to print in black & white. Not only did it mess up the copies I was printing, so that they were only usable as drafts, but I was unable to just remove the cartridge (or replace it with an old spent cartridge) and print in black and white since the CP2025 printer requires that a non-empty cartridge be present to work at all.
Excerpt: I use the toner in a home-based business -- photography/printing. While most of my photographic work merits the use of an ink jet, to use an ink jet on brochures, book-type projects would be economically prohibitive. Maybe it is the printer, but the results with this toner are really good for a laser color print. Clients have been most pleased. Only con is, of course, the cost.
