LaserJet 4300

HP positioned the LaserJet 4300 in 2002 as the step up from the 4200: more speed and more capacity on an A4 monochrome engine, aimed at offices whose daily volume had outgrown the smaller machine. Its supplies could not be simpler — one cartridge does everything. The 4300 runs on the Q1339A, HP's 39A, and every listing on this page is a build or a bundle of that single code.

That one-code design is the base 4300's quiet advantage two decades on. There is no standard-versus-high-yield decision to research and no second cartridge for a drum; the only real choices are how the cartridge is built — standard, premium or MICR — and how many of them arrive in the box.

Which cartridge should you buy?

With a single code on the shelf, the decision is about quantity and build. A lone 4300 in a small office does fine on singles, ordered as the level warning appears. Busier sites should think in packs: the two and three packs keep a spare beside the machine, and the five packs — standard or premium build — suit a printer whose monthly volume is measured in reams. The premium build is the same code with a higher-grade construction for offices that print all day. Choose the MICR row only for check printing; its magnetic toner is a specialty fill, not a general upgrade.

Chip, toner and everyday use

A chip on the cartridge reports its level to the printer, and a compatible cartridge that clicks fully into place is recognized straight away. When pages start to fade, lifting the cartridge out and rocking it gently from side to side levels the toner that remains and often restores even coverage for the rest of the run. Store spares sealed, flat and away from windows; toner tolerates a long shelf life when it stays dry and out of the heat. If toner spills, wipe it with a dry cloth — water sets it into fabric and makes a small mess permanent.

Frequently Asked Questions

Which toner cartridge does the LaserJet 4300 use?

The Q1339A — the 39A — in every case. If an older note names a different code for this printer, trust the cartridge you pull out of the machine: it will read Q1339A.

Is there a high-yield version of the 39A?

This shelf carries one code in several builds and pack sizes rather than a separate high-yield code. For longer runs between orders, the multi-packs of the 39A are the practical step up.

What does the MICR cartridge do?

The Q1339A MICR build uses magnetic toner so the account line on printed checks can be read by bank scanners. For ordinary office documents, the standard build is the right choice.
