Compatible HP OfficeJet Pro K550 K5400 L7000 Ink

Looking for ink for your HP OfficeJet Pro K550, K5400 or the L7000 series? The compatible cartridge you need is the HP 18XL / 88XL. Our compatible version yields 600 pages with the same print quality as the original, and costs a fraction of what you'd pay for the brand-name option. See the compatible ink cartridge.

Is it compatible with your printer?

The HP 18XL / 88XL cartridge is the consumable used by a whole family of OfficeJet Pro machines, across both the K series and the L series. If your printer is any of these models, this is the ink you're looking for. Pay attention to the letters at the end of the name: dn adds network connectivity (ethernet) and duplex printing, and dtn adds an extra paper tray on top of that; the base number (for example K5400 or L7580) identifies the print engine, which is what determines the cartridge you need. All of these variants use the same consumable.

The consumable you need and how much it yields

Startoner's compatible HP 18XL / 88XL ink cartridge yields 600 pages measured according to the ISO/IEC 24711 standard, the international benchmark that defines the yield of inkjet cartridges. That figure lets you compare apples to apples: it's the same standard used to measure original cartridges, so the 600 pages are directly comparable.

Since this is the high-capacity version (XL), it holds more ink than a standard cartridge, so you print more before having to replace it and you lower your cost per page. It's the ideal choice if your OfficeJet Pro is your everyday workhorse and you print in volume. Check the product page and the current price of the cartridge here.

Remember that we're talking about ink, not toner: these OfficeJet Pro machines are inkjet printers, so the consumable is liquid and comes in cartridges, not powder. If you're unsure about the differences, we explain it all in our ink cartridge vs. toner guide.

How much printing costs you

Here's the key point: a compatible cartridge yields the same 600 ISO pages as its original equivalent, but at a fraction of the price. Page for page, printing with compatible ink works out much cheaper without giving up the quality or the reliability of your printer.
