We buy far only the original ink cartridges for our HP Officejet 6700. The printed image is great, the color is not blurred and the few pictures I've printed out, looked really great. The cartridges hold in our consumption about 1 year. This is actually, but I'm surprised because I do not think that we print so much in color. I "heart bleeds" when I sometimes hear when the printer's cleaning run o. Ä making. Because I always imagine how he now paint sprayed pointless. But is also strange that within a few days all the colors, even the large black cartridge, at the same time be empty. ("Evil to him who evil thinks!") Well, I think that the cartridges can be recycled for free.
