HP OfficeJet Pro 9720e Ink Cartridge FAQs

Why are ink cartridges so expensive?

OEM ink and toner manufacturers claim that the high cost of toner cartridges is due to the research and development of technologies to deliver high-quality ink and toner. However, it is worth noting that there are generic cartridges that exceed OEM requirements while being less expensive than their counterparts. CompAndSave's compatible and replacement ink and toner cartridges are engineered to meet or exceed OEM standards. That is to say, you can have the same print quality and page output without spending a fortune. Please keep in mind that using generic, remanufactured, or replacement cartridges will never void the warranty on your printer. For additional information, please visit ink knowledge base and you will be redirected to the right page.

How do I get my HP printer to accept compatible cartridges?

Compatible, replacement, or remanufactured cartridges are usually plug-and-play and don't need any changes in settings to work. But in case you encounter an issue wherein your printer will not accept it, the first thing to check is if you have purchased the correct model number of cartridge for your printer. To verify this, just check the printer's manual or the old cartridge installed in your printer and look for the model number, which usually consists of alphanumeric characters. Once verified and you're still having the same issue, the next thing to do is to turn off the printer for at least 15 minutes, then wipe the copper or chip part of the cartridge with a non-abrasive towel or cloth with alcohol. Reinstall it in your printer and see if it works this time. To learn more, check our Troubleshooting Tips, and you will be redirected to the right page.

    Review for Replacement HP 936e Black Ink Cartridge - 4S6V6LN - High Yield
    Jan 10, 2026
    Verified Buyer
    Your cartridges are almost always good quality. It’s a shame that I need to open my printer door several times before the HP printer will go ahead and print. I’ll never buy another printer that almost demands you buy their ridiculously expensive cartridges again.
