HP 125A is a four-colour toner family for selected HP Color LaserJet printers. Use the code on the cartridge already fitted and your printer’s complete model number to check the right colour and replacement. Compatible cartridges are third-party products, so confirm the supplier’s exact product listing rather than assuming every 125A-labelled product is identical.

HP’s published yield statement for the CP1515n/CP1518ni reports a declared yield of approximately 2,200 standard pages for black and a composite cyan, magenta and yellow (CMY) yield of approximately 1,400 pages under ISO/IEC 19798. See HP’s 125A yield statement. These are original HP reference figures, not a guarantee of pages and not the yield of a compatible or remanufactured replacement. Print coverage and use affect actual results.
Printer models to check
HP’s support information associates the 125A code family with selected models in the Color LaserJet CM1312, CP1210 and CP1510 families. Listed examples include CM1312 and CM1312nfi, CP1215 and CP1217, plus CP1514n, CP1515n and CP1518ni. Model suffixes and regional versions matter: check the full model against HP’s cartridge compatibility guidance and your printer’s support information before buying.
Choosing an original or compatible replacement
- Match the complete code and colour, not just “125A”.
- Check that the listing names your exact printer model.
- For compatible or remanufactured options, use that product’s own yield, warranty and returns information—not HP’s original-cartridge figures.
- Confirm current stock, total price, delivery terms and returns before ordering.
Search the online catalogue for CB540A. Search the catalogue again using CB541A, CB543A or CB542A for the other colours. If you cannot confirm a match, ask us before ordering.
