Which toner fits the HP LaserJet M433a?

Almost four months per cartridge

The interesting figure is not the yield on its own, but its ratio to the volume. HP recommends up to 2,000 pages a month here for a toner of 7,400: at full tilt, one cartridge covers close to four months.

That is the best ratio in the catalogue, and the exact opposite of small standby lasers such as the LaserJet Pro M15a, whose 1,000-page toner corresponds precisely to one month of recommended use. On the M433a, the consumable is not what sets the rhythm of the machine's life — you will reload paper dozens of times between cartridges.

That changes how to stock up: one spare cartridge covers six months, and there is no point holding more.

It has neither Wi-Fi nor a network port: the connection is over USB. It does show its state on a four-line LCD, though — a lot for this class, where a single indicator light is the rule, and enough to read the toner level without going near a computer.

It prints at 20 pages per minute and holds 350 sheets across two trays, 100 and 250. Its maximum cycle reaches 40,000 pages a month, a mechanical limit unrelated to the recommended volume.

When should it really be replaced?

When pale areas appear, not at the warning. On a 7,400-page toner, the low-level message comes several hundred pages before the real end. Take the cartridge out and rock it gently from side to side: the remaining powder redistributes and often gives another good hundred pages.
