Interestingly, businesses which are "renting" their big laser color multi functions printers are on a contract.
This means that no matter what the coverage is and how many laser cartridges they chew in a billing cycle, they are charged per page printed! Full coverage prints only cost the company the same as a 5% coverage.
So check with your company and if this is the way they are charged, maybe ask if you can do some "private" printing and pay per sheet printed.
At an individual level even a monochrome laser printer ends up being very costly. I have a Samsumg 2835DW that is cheap to buy (less than $100). It came with a start-up toner installed advertised for 600 pages at 5%. My wife uses it a lot for her master degree and we printed almost 1,000 pages on that cartridge.
We then purchased compatible cartridges which are almost 40% cheaper than the genuine Samsung. The high-capacity are advertised for a 3,000 page at 5%.
Well, it ran out after just about 745 pages! Same printing habits. Nothing fancy, no big pictures or graphics in the printed articles. We would have expected something like 4,000 from a 3,000 yield advertised!
At $55 a pop, that makes the sheet printed cost 7.5 cent/page! Ouch... Plus the drum cost per page!
Be prepared for high cost when running any laser printer (color or mono) at home.
