We get quite a few enquiries about XL ink cartridges as it can be difficult to understand why ink manufacturers produce two such cartridges that are for the same printer but appear to be different sizes. The simplest way to explain this is to say that the XL cartridge (despite the name) is actually the same external size as the standard cartridge but they differ in their internal capacity. 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.
