LaserJet 4300TN

Networking plus an extra paper tray made the LaserJet 4300TN the workhorse configuration of the 4300 series — the version departments that measured printing in thousands of pages chose for its stay-fed design. It draws on the family's single cartridge, the Q1339A, HP's 39A.

The TN formula attacks the two interruptions that dominate a busy printer's life: empty paper and an empty queue spot. With both handled, toner becomes the one consumable left to plan — and on a machine fed by the ream, toner planning means packs, not singles, and a spare that lives where the paper lives.

Which cartridge should you buy?

Let the tray capacity set the rhythm. A TN that swallows paper by the ream will work through cartridges at a matching pace, so the three pack is the natural unit of purchase: one in the printer, one beside it, one in transit. Sites running the TN as a department's main engine should consider the five packs, choosing the premium build when output runs all day without pauses. Singles remain right for a TN in a quieter corner, and the two pack is the minimum sensible insurance for any shared machine. As ever on this shelf, the MICR build is the check-printing specialist, not a volume play.

Chip, toner and everyday use

Level reporting comes from the cartridge's chip, so the low warning is data, not a guess — act on it the day it appears and a TN never stops a department mid-run. A cartridge that fades early usually just needs its toner leveled: out, a gentle side-to-side rock, back in. Store the spares flat and sealed alongside the paper stock; the same dry cupboard that keeps paper crisp keeps toner dependable, and co-locating the two consumables means whoever feeds one notices the other.
