Frequently Asked Questions

Will the C4837AN ink cartridge void my HP printer warranty?
No. Under the U.S. Magnuson-Moss Warranty Act, HP cannot void your printer warranty solely because you installed a compatible (non-OEM) ink cartridge. The C4837AN is designed to drop in as a direct replacement for the OEM part.

How does print quality compare to the genuine HP C4837AN?
The C4837AN is engineered to match the OEM cartridge's ink chemistry and head-firing characteristics, so day-to-day output should look essentially identical to the original HP C4837AN. If you ever see a difference, our 100% satisfaction guarantee covers a free replacement or refund.

Which printers use the C4837AN?
The C4837AN fits a range of HP models (HP OfficeJet series), including the BUSINESS INKJET 1000, BUSINESS INKJET 1200, BUSINESS INKJET 2800. The full compatibility list is in the Compatible Printers section above - check your printer model there before ordering.

At $16.95, the Castle Ink C4837AN is about 52% less than the typical OEM retail price of $34.95. For users printing regularly, that saving compounds quickly across replacements.
