Buying the right HP 128A toner is simple once you know three things: the printer models it fits, the page yield of each version, and how the price per page compares. Here is all of it in one place. Every cartridge listed below is a genuine HP original, brand new and factory sealed, with free shipping across the USA.
Which printers use HP 128A?
HP 128A cartridges are made for the following HP printers:
- HP LaserJet Pro CP1525n, CP1525nw
- HP LaserJet Pro CM1415fn, CM1415fnw
Tip: the model number is printed on the front or top of the printer and on the sticker inside the toner door. If your model is not listed here, check the cartridge number on the old cartridge itself — HP prints it on the label.
HP 128A cartridge lineup
| Cartridge | Part number | Color | Page yield* | Price | Cost per page |
|---|---|---|---|---|---|
| HP 128A Toner Cartridge | CE320A | Black | 2,000 pages |
|
4.0¢ |
*Yields are HP's declared values (ISO/IEC 19752 for mono, ISO/IEC 19798 for color) at 5% page coverage. Real-world yield depends on what you print: dense graphics use more toner than text.
Multipacks: when they pay off
| Pack | Cartridges | Pack price | Bought singly | You save |
|---|---|---|---|---|
| HP 128A Toner Cartridge 2-Pack | 2 |
|
$162.00 | 3% |
Every cartridge in a GS TONER multipack is the same genuine HP 128A sold individually — full yield, same packaging, same warranty. Packs make sense when you already know you will use every cartridge within about a year; unopened HP toner stores well for at least that long in its sealed bag, away from heat and sunlight.
How long will an HP 128A last you?
Use your monthly page count (the printer's usage page reports it) to see how often you will change cartridges and what toner costs per month with each version.
| Monthly volume | 128A: cartridge life / toner cost per month | High-yield |
|---|---|---|
| 250 pages | 8.0 months / $10.12 | — |
| 500 pages | 4.0 months / $20.25 | — |
| 1,000 pages | 2.0 months / $40.50 | — |
| 2,000 pages | 1.0 months / $81.00 | — |
Below about 166 pages a month a cartridge would sit in the printer for more than a year, so the standard version is the better fit; above 666 pages a month the high-yield version (if one exists for this family) pays back quickly and halves the number of cartridge changes.
Genuine HP vs compatible HP 128A
Search results for “HP 128A” are full of compatible and remanufactured cartridges at a fraction of the price. They can work, but the trade-offs are real: yield claims are not measured to the same ISO standard, toner formulation differs from the one the fuser was tuned for, chip errors after firmware updates are common, and a leaking cartridge can put a drum or fuser repair on your bill. HP's warranty does not cover damage caused by non-HP supplies. We sell only original HP cartridges — the ones with HP's security label — because for a workgroup printer the difference in cost per page is small next to the cost of downtime.
How to check yours is genuine: the box carries a HP security label, the cartridge has HP's part number (CE320A for the 128A) molded or printed on it, and the printer's supplies page identifies it as an original HP cartridge after installation.
Replacing the HP 128A cartridge
- Open the cartridge door (front or top, depending on the model) and pull the old cartridge straight out by its handle.
- Take the new cartridge out of its bag. Rock it gently end to end five or six times to distribute the toner — do not shake it vertically.
- Remove the orange shipping clips and pull the sealing tape straight out if the cartridge has one (many current HP models do not).
- Align the cartridge with the guides and slide it in until it seats; close the door. The printer calibrates for a few seconds and reports the new cartridge on the supplies page.
Keep the old cartridge for recycling: HP Planet Partners takes back original HP cartridges free of charge in the US.
