Query: pretty cool and not expensive

The picture quality is very good for such a budget printer. I purchased mine primarily for text printing and am using the BC-20 black print head which has a very large tank (good for aprox. 900 pages of text) compared to the much smaller tank of black ink (good for aprox. 225 pages of text) that is on the BC-21e color print head that is included with the printer. The BC-20 prints black text faster than the color head as it has 128 nozzles for black compared to 64 black nozzles on the BC-21e. The color head has replacable color and black tanks which are cheaper to replace than buying the entire print head. The print head is very easy to replace. It just drops into a slot and a lever is pulled forward to lock it into the holder.
