Why this answer matters
HP uses many visually similar cartridge families. Checking the exact model-to-supply relationship reduces the risk of buying an incompatible cartridge based only on printer series or retailer filtering.

Requirements
What has to be true
- Use the 936/936e family listed by HP for the U.S. OfficeJet Pro 9125e model.
- Confirm regional cartridge numbering if the printer was purchased outside the market of the cited HP page.
- The printer uses four color positions: black, cyan, magenta and yellow.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Confirm the model is OfficeJet Pro 9125e rather than a nearby 91xx-series variant.
- 2
Use HP's supplies/specifications page to match the cartridge part number in your region.
- 3
If output is streaked or missing a color, print a controlled color/grayscale page before ordering multiple replacements.
Limits
What this answer does not prove
- Availability and regional part numbers can change; the cited HP model page is the authority for the referenced market.
- Compatibility does not diagnose clogged nozzles, printhead faults or a defective cartridge.
