Product Description
The HP CN045AN compatible black ink cartridge from Castle Ink is a direct replacement for the OEM HP CN045AN, built for HP OfficeJet Pro inkjet 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 CN045AN 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 CN045AN 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 CN045AN with a 100% satisfaction guarantee: if you aren’t happy with quality or yield, we replace or refund it.

Frequently Asked Questions
Will the CN045AN 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 CN045AN? The CN045AN 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.
Frequently Asked Questions About HP 950 and HP 950XL Ink
Which HP printers are compatible with the HP 950XL (CN045AN) black ink cartridge? The HP 950XL black cartridge works in the HP OfficeJet Pro 251dw, 271dw, and 276dw, the OfficeJet Pro 8100, and the OfficeJet Pro 8600 series (8600, 8600 Plus, 8600 Premium, 8610, 8615, 8620, 8625, 8630, 8640, and 8660).
What's the difference between HP 950 and HP 950XL ink cartridges? Both cartridges are the same physical size and fit the same printers, but the 950XL holds more ink. Standard HP 950 black cartridges print up to about 1,000 pages, while the 950XL delivers roughly 2,300 pages — more than double the yield.
Are HP 950 and HP 952 ink cartridges interchangeable? No. HP 950 and HP 952 cartridges use different physical designs and are built for different printer families, so a 950 or 950XL cartridge won't fit or lock into a printer designed for HP 952 ink, and vice versa.
How many pages does the HP 950XL black ink cartridge print? The HP 950XL black cartridge is rated for approximately 2,300 pages at 5% page coverage, more than double the yield of the standard HP 950 black cartridge.
