Which ink does the HP DeskJet 4155e use?

The DeskJet 4155e runs the HP 67 family. That is HP 67 black and HP 67 tri-color at the standard size, HP 67XL black and HP 67XL tri-color at high yield, and the number printed inside the cartridge door settles any argument with a listing.

A cost per page only means something next to another one. An HP 67XL black puts a page down for 15.00c. Two other HP machines in our catalogue do the same office work for very different money: the OfficeJet Pro 6978 runs an HP 902XL at 4.61c and the OfficeJet Pro 7740 runs an HP 952XL at 2.25c. A black page on this printer costs close to seven times what the 7740 charges and more than three times the 6978. Among the 90 inkjet black cartridges we price, the 67XL ranks 86th from the cheapest and the plain 67 ranks last.

High yield helps and does not rescue it. The 67XL black is rated 240 pages for $35.99 while the plain 67 is 120 pages for $22.99, which works out at 15.00c against 19.16c, about 22 percent off, plus half as many trips to the shop. The tri-color side saves a similar 23 percent. A standard pair is $46.98 and an XL pair $72.98.

On any other printer the answer to a 15.00c page is a compatible cartridge, and that is exactly what this one forecloses. The 4155e ships enrolled in HP+, which uses Dynamic Security to insist on original HP supplies, and enrolment is chosen during first setup rather than reversed afterwards. If your machine is already enrolled, genuine HP 67 is the buy and the saving has to come from printing habits instead: draft quality for anything internal, and the tri-color left in place rather than swapped out early. Our firmware DRM tracker lists the models HP has enrolled this way.

Distinguishing a real fault from a refused cartridge saves money here. A contact fault wanders, clears when you wipe the copper strip with a dry cloth, reseat the cartridge and leave the printer unplugged for a minute, and often follows a cartridge that still has its plastic tape on. A refusal tied to enrolment appears immediately and stays. Banding and washed out colour belong to neither group and usually mean the printhead needs a cleaning cycle, which is worth running before a cartridge with ink in it goes in the bin.
