The Canon PG-540 XL is a high yield ink cartridge that contains almost 3.5x more ink than the standard version. However, this doesn’t mean the cartridge is a different size. XL cartridges have been designed to fit the same space as a standard version but to hold more ink. This makes the PG-540 XL black great value for money as it can squeeze out 600 pages worth of documents instead of a maximum of 180.
