Hi, I've added a listing on the product page that displays which cartridges go in the printer and their costs.
For running costs, it really depends on what your initial budget is, this machine is in the middle of the pack for cost per page on toners (around 2-3p per page in mono). There are more efficient machines like
https://www.tonergiant.co.uk/product/Xerox-C305ae-A4-Multifunction-Colour-Laser-Printer-C305VAEUK-102437/ which give a lower cost per page but the initial printer price is more, and toners are more expensive but more cost effective in the long run as they have a cheaper cost per page (less than 2p per page in mono).
Most of the more efficient printers tend to cost at least £100 more initial cost and more expensive toners.
