The genuine HP 304XL ink cartridge is designed for high-volume users as it consists of over twice the amount of ink that normally exists in a standard HP 304 ink cartridge. The HP 304XL is just as easy to install as the standard capacity version but provides you with a yield of up to 300 pages. Being an original Hewlett Packard product, it is of the highest quality and comes straight from the manufacturer. It has its own print head, so the ink comes directly from the HP 304XL to your paper. All print documents created with the HP 304XL black ink display rich, black text in high volumes.
