Basically, the text, whether set large scale or small, prints like the cartridge is finished. Just replaced it, and pre-Ubuntu switch .pdfs, and all other doc formats print just fine. Pretty frustrating. Have tried the MP250 onboard cleaning etc, and altered about every setting I can think of. I have been forced by a nerd girlfriend onto ubuntu and this is one of many niggles that's niggling hard as I do a lot of printing and research paper reviewing and cannot stand more than 20 pages of continuous text. Any ideas?
