Too bad HP (like the others) flange compatible, that does not stop the operation, some deterrent messages on hoopla ... guaranteed at the time of change of cartridge then the printer works. But suddenly the printer no longer displays the ink level, will guess which is the ink that is lacking or spend pages of tests ... and where the low Blese is to do the manually cleaning cycles which wastes a sheet each time. Anyway it's better that the origins cartridges so expensive that almost cost the purchase price of the printer every time you change cartridges. The black picture provided 2 does not sound compatible with my printer (photosmart 552x) after a few weeks the first yellow began to make short orange .... enthusiastic at first I returned edit my review, it has for its money, that is not much.
