Has anyone got a good list of the costs of running colour laser printers, both for colour and black that take into account different usage volumes.

E.g if the dram needs replacing after 20,000 pages, but I am only do 10,000 in the next 3 years, I don’t care about the cost of a new dram.

So a simple “cost per page” figure is each printer is not good enough to be useful in real life.

(A spread sheet / website that I could type my own usage values into would be great.)
