Product Description
The HP CB321WN compatible black ink cartridge from Castle Ink is a direct replacement for the OEM HP CB321WN, built for HP LaserJet, OfficeJet, DeskJet or DesignJet office printers. It’s an economical way to keep your printer in service without paying full OEM prices, while still meeting the print-quality standards your team expects.
The CB321WN delivers dense, dark black for sharp text, line work and reliable bar-code scanning. Castle Ink uses pigment-grade carbon black where the OEM specifies pigment ink so output looks crisp at first print and stays consistent through the life of the cartridge. Every CB321WN is assembled with a sealed ink reservoir, OEM-spec print-head interface, and color-balanced ink, then individually tested before shipping. Castle Ink backs every CB321WN with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions
Will the CB321WN void my HP printer warranty? No. Under the U.S. Magnuson-Moss Warranty Act, your printer manufacturer cannot void your warranty solely because you installed a compatible (non-OEM) cartridge.
How does print quality compare to the genuine HP CB321WN? The CB321WN is engineered to match the OEM cartridge’s ink chemistry, density and head-firing characteristics so day-to-day output should look essentially identical. If you ever see a difference, our satisfaction guarantee covers a free replacement or refund.
How fast will my order ship? Orders placed before 2pm ET ship the same business day from our U.S. warehouse with free standard shipping. Expedited options are available at checkout.
