You'd think you could flush with water or some such after orint, as long as it was pure h2o (no minerals, etc) One flush after each print, but sadly, no manufacturer cares I guess.
Every now and then I'd like to print out a map or whatever in color but it's just not often enough to maintain an inkjet printer.
If everyone who did that just bought a brother B&W laser just once instead of re-upping their inkjet I bet anything the consumer market for cheap inkjet printers would disappear forever. Inkjets would only survive as a high end commercial colour technology.
