So, whether you have an older model such as HP Deskjet 3070a or a newer model like HP PhotoSmart eStation All-in-One, you can buy either HP 564 or 564XL ink cartridges when your first set of cartridges run out of ink. In other words, these cartridges are interchangeable.

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.

Alternatively, you can look for the printer cartridge number or cartridge type in your printer's manual. If you no longer have your printer's manual, you might be able to find this information online by doing a search for your printer's model number, which is often found on the printer itself.

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.
