UCI Compatible Toner Cartridge Replacement for HP CE278A 78A (2100 Pages) - Black

It works! Crisp, black printing - not sure the last one gave me quite the HP number of prints, though given the saving this is not an issue in the slightest.

I was a bit dubious before I bought this, as the price was so ridiculously low compared to the HP price.My doubts were completely unfounded. Does the job perfectly. This is a quality product, and costs peanuts. Just ordered another for stock, even though after three months the cartridge is still doing fine.
