HP's cartridge names end in a letter: 26A and 26X, 58A and 58X, 414A and 414X. Buyers regularly assume the X is a premium grade or a different cartridge. It is neither. The letter tells you how much toner is inside — and that single fact decides most toner purchases.
Key takeaways
- Can I use HP 58X instead of 58A? Yes. A and X cartridges of the same number fit the same printers and print identically; the X simply holds more toner and reports a higher capacity.
- Is HP X toner better quality than A? No. Same toner, same drum, same print quality. The only differences are the amount of toner, the price and the cost per page.
- What do HP letters like J, JC or L mean? J and JC are extra-high-yield versions of some enterprise cartridges; L is a lower-capacity version. A is standard and X is high-yield across the LaserJet Pro range.
A = standard yield, X = high yield
An A and an X of the same number share the same shell, drum, chip design and toner formulation and fit exactly the same printers. The X contains more toner (sometimes a slightly larger hopper) and its chip reports the larger capacity to the printer. Print quality is identical because everything that determines quality is identical.
| Family | A yield | X yield | Ratio | Printers |
|---|---|---|---|---|
| HP 26A / 26X | 3,100 | 9,000 | 2.9× | LaserJet Pro M402, MFP M426 |
| HP 58A / 58X | 3,000 | 10,000 | 3.3× | LaserJet Pro M404, MFP M428 |
| HP 87A / 87X | 9,000 | 18,000 | 2.0× | LaserJet Enterprise M506, MFP M527, Pro M501 |
| HP 414A / 414X (black) | 2,400 | 7,500 | 3.1× | Color LaserJet Pro M454, MFP M479 |
| HP 206A / 206X (black) | 1,350 | 3,150 | 2.3× | Color LaserJet Pro M255, MFP M283 |
Why the X is cheaper per page
The expensive parts of a cartridge are the drum, rollers and chip — the same in both versions. Toner is the cheap part. So the X costs perhaps 1.6–2× the A while printing 2–3.3× the pages, and the cost per page drops by 30–45%. For a printer that prints a few thousand pages a year the difference is worth hundreds of dollars.
When the A still makes sense
- Very light use. If a cartridge would sit in the printer for two or more years, buy the A. Toner settles and drums age; a fresh A every 18 months beats a tired X.
- Cash flow. The A's lower upfront price matters for some small offices; just know it costs more over time.
- Color cartridges you rarely use. On a color printer that prints mostly text, buy X black and A colors.
- Printer near end of life. No point loading 10,000 pages of toner into a printer you plan to replace next quarter.
Other letters you will see
J / JC — extra-high-yield versions of some enterprise cartridges (HP 37Y, 89Y and similar use Y). L — a reduced-capacity, lower-priced version sold in some regions. M — managed-print versions sold under contract, which are not meant for retail printers. If the number matches but the letter is unfamiliar, check the part number on your printer's supplies page.
Bottom line
Unless the printer is barely used, buy the X. It is the same cartridge with more inside, and the cheapest genuine toner per page you can put in that printer.
