I prefer the HP inks for a few reasons: 1) they are the least expensive part of the printing, 2) I have used bargain inks in the past only to find that they lack the vibrance of color, don't last as long, and/or stop working due to a flaw in the compatibility chip in the cartridge, and 3) if I encounter a problem with any cartridge, HP stands behind their products and it is replaced immediately. Lastly, I'm using an HP plotter that I invested a lot of money into. I will not use an off brand ink to save a few bucks when I might actually void my warranty for the plotter. Why would I? Why would you?
The printer gives NO HINT AT ALL the ink is running low, so it STRANDED ME IN THE MIDDLE OF A MASSIVELY IMPORTANT DEADLINE JOB. Of course it was BLACK ONLY PRINTING, but God forbid you run out of cyan and the whole farcking machine quits on me. Whomever designed this machine SHOULD BE TAKEN OUT BACK AND SHOT. I expected more from HP.
