Question about Brother Tn-2000

Some printers (software) have a counter that you can query (and reset). Unfortunately, you don't have many other ways to check it.... Coverage is very difficult to check. There are some comparisons online that test the maintenance costs of printers, but even that should be taken with a grain of salt. The toner itself has nothing to do with the consumption. It is a question of a quantity, such as 1 litre of water. You could also say that this is enough for 100 "normal" gulps - if you can do that in 90, you didn't get less!
