What ink can work in a dell 922 printer?

Dell printers are proprietary printers. Basically this means, you have to use original inks. There are no compatible cartridges for them (at the moment).

The ink no's for the printers are as followed

High Capacity Black - M4640
High Capacity Colour - M4646
Low Capacity Colour - J5667
Low Capacity Black - J5566
Photo Ink - J4484

When looking for inks, please shop around. Do not just go for the first price you find, as the prices vary enormously.

Hope this helps

Be safe
