Can I use a different number ink cartridge for my HP printer?

No, you can't. Each HP printer has a designated ink cartridge for them. These cartridges have different sizes, yields, and compatibility. Your printer will not recognize the cartridge if it's the wrong one. Using the wrong ink cartridge on your HP printer might cause some issues. To know the model number of the cartridge your printer is using, you may check the user's manual that came with your printer. You may also check the existing cartridge that is installed in your printer. In front or on the side is a label or sticker with the model number, which is usually consisted of alphanumeric characters. If you need help finding the ink cartridge for your printer, you can check our guide What ink does my printer use?, and you will be redirected to the right page.

Why is HP printer ink 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.

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.

    Was an unexpected treat being able to find cartridge no longer stocked at the big office supply stores (for a largely obsolete printer!). These remanufactured cartridges seem to work fine and pricing from CompandSave is VERY competitive! Questions were promptly answered by capable associates with product shipped promptly. No complaints!

    When I needed ink, Comp and Save was temporally out of this product so I ordered from another vendor. The cartridge I received from the other vendor did not work. I called and they sent me a second cartridge. That didn't work either. By this time, Comp and Save had this back in stock and as usual, it works in my old HP Desk Jet 932C. Thank You Comp and Save!
