ok, on the same theme of buying a printer and trying to work out (eventually) the cost per page..
say a toner cartridges average lifespan is 25,000 pages,
and you need a black cartridge and three colour cartridges..
Do I work this out multiplying their lifespans together? Does this make sense?
25,000 pages each, four cartridges = 100,000 pages total?
Am I way off the mark here?
