HP 915 Inkjet Ink Cartridges
Your HP 915 Inkjet uses the 21 / 22 cartridge series, which operates on a simple dual-cartridge system containing one black cartridge and one tri-colour cartridge. We have been supplying reliable printer consumables for this system since Sep 2009. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance. For home users, print tasks often cause the integrated ink chambers to deplete unevenly depending on your household document styles.
What to expect from each cartridge type
Standard outputs deliver yields of 185 pages for the black cartridge and 170 pages for the tri-colour setup. These targets follow standard ISO/IEC 24711 measurement practices, although actual print counts are influenced by font selections and colour saturation levels.
What to know about compatible cartridges
Utilising premium compatible cartridges provides an excellent opportunity to reduce household running costs without risking damage to your printer. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty.
Choosing the right cartridge setup
If you print mainly text documents, purchasing standalone black cartridge replacements is the most straightforward choice. If you print colourful graphics or school projects, choosing a bundle pack decreases your upfront costs. All premium compatible products are fully covered by a robust money-back guarantee. Free delivery applies on all orders over $99 (conditions apply). We pack and ship directly from our national warehouses in Sydney, Melbourne, Brisbane, Adelaide and Perth. Browse the full range of items on our HP ink cartridges page, and consult our returns policy for processing terms.
Pro Tip
The tri-colour cartridge features three distinct internal wells for cyan, magenta and yellow ink. Because this system reads the cartridge as empty as soon as a single colour path runs completely dry, managing your document background tones prevents you from disposing of a cartridge that still contains remaining ink in its other chambers.
Frequently Asked Questions
Can I use high-yield 21XL or 22XL cartridges in my printer if I previously used standard 21 and 22?
Yes, high-yield XL cartridges feature identical physical sizes and structural dimensions to the standard versions. They simply contain a larger internal ink reservoir, allowing them to fit into the exact same cartridge carriage slots.
Why does my computer show a low ink warning immediately after I install a new compatible cartridge?
Older printer memory structures occasionally cache previous cartridge details and report an incorrect supply alert. You can typically override this signal and resume printing by holding down the Cancel or Stop button on the printer panel for five seconds.
Will the ink nozzles dry out and block if the printer is left unused for several weeks?
Yes, because the printing nozzles are integrated directly onto the base of the 21 and 22 cartridges, sitting idle allows residual fluid to dry out. Running a quick single-page check print once a fortnight keeps the internal pathways clear.
