A: The 910 & 910xl ink cartridges are the same size and same shape. The XL version has more ink inside.

825 pages Page Yields: black up to 825 pages, each color up to 315 pages.

An XL cartridge is capable of holding more ink and is, therefore, able to print more before running out. XL ink cartridges cost a little more than their standard sized counterparts but the increased amount of possible prints offsets this cost and makes them a more economical choice in most cases.

"Ink companies spend a lot of time to get the right blend of pigment, dye, and vehicle to be able to have a very stable small droplet for high-resolution printing," Williams says. All of that research and development, of course, costs a lot of money - and that's where the price comes in.

Although the cartridges look similar, their compatible printer model are completely different. The printer model of different cartridge may be different. But 910 standard yield and 910xl high yield ink cartridge are compatible with the same printer model, so 910 and 910xl can be used interchangeably.

The main difference between the two is actually the amount of ink in each cartridge. Standard ink cartridge contains less ink and is, therefore, less expensive than high yield cartridge. XL or high yield cartridge contains more ink and therefore can be used to print more pages at a better value per page.

So, are XL ink cartridges worth buying? As mentioned above, XL cartridges are more expensive than standard cartridges. That said, they are also more cost-effective because the average cost per page is lower, making them a good choice for people who print frequently or who want to save money in the long run.

The main difference between the two is actually the amount of ink in each cartridge. Standard ink cartridge contains less ink and is, therefore, less expensive than high yield cartridge. XL or high yield cartridge contains more ink and therefore can be used to print more pages at a better value per page.

Although both contain a microchip and print head, the larger ink chamber stores more ink, so the cartridge can print more pages than a standard cartridge. High yield cartridges are identified with the letters XL after the model number for HP inkjet cartridges.
