HP has one of the strongest secondary markets we’ve seen. Although the 8600 came out way back in 2012, its current used price of around $154 on Amazon isn’t too far off from the $250 launch price. Don’t get us wrong: it’s a good deal for a cloud printing model that does its job well, especially if you can get one in good condition.

With something this sturdy, you aren’t likely to run into a lot of HP printer not printing black issues or general malfunctions. Getting ink, however, might be another issue. With so many years having gone by since its release, HP Officejet Pro 8600 ink has been getting harder to find, which is why many users opt for remanufactured ink.

HP certainly didn’t make this easy, as the manufacturer made the 8600 incompatible with the HP Instant Ink program. Without it, you’re sort of left to your own devices. The HP Officejet Pro 8600 manual won’t tell you how to refill those cartridges in any sensible way. Fortunately, we’re here to help.

What is the best HP Officejet Pro 8600 ink cartridge?

With a model like this (non-colored), replacing ink cartridges can be a bit confusing. HP brands the compatible ink cartridges with 950, 950XL, 951 and 951XL, but they’re often grouped together with colored ones, which you won’t have much use for. Our suggestion is that you check the Amazon listing for HP Officejet Pro 8600 ink and get the cartridge(s) labeled 951XL black. These should serve you long enough and remain available for some time, as they tend to be the most popular variation.
