Which ink/toner does the HP LaserJet Pro MFP M428fdw use?

The LaserJet Pro MFP M428fdw is the wireless version of HP's 58A multifunction.

Toner comes in two sizes and only one of them is worth buying regularly. 58X works out at 1.79c a page against 3.17c for the 58A, and the machine is fast enough that most owners get through the small cartridge quickly. Budget for the drum as well: this model keeps its imaging drum separate from the toner, with its own counter and its own bill, which our guide to drum units against toner covers.

This is one of the models HP flags as dynamic security enabled, so it is intended to work only with cartridges carrying a new or reused HP chip and firmware updates can withdraw support for a compatible cartridge you already own. It sits on our firmware lockout tracker alongside the rest of the 58A generation.

Remanufactured cartridges deserve a separate thought on a locked model. HP's own wording says a reused HP chip enables the use of reused, remanufactured and refilled cartridges, so a remanufactured 58X built on a genuine HP chip sits in a different position from a new build carrying a cloned one. It costs more than the cheapest compatible, and it is the option most likely to survive an update.
