Correct. I bought this laser printer that uses a drum instead of ink. Drums are good especially if you do not use it often as it does not dry up like ink. Printing is faster with drums too.
Brother Monochrome Multi-Function laser Printer DCP-2540DW was my model.
Bought it back in 5th January 2016. Now is 2018 and I am still on my 1st drum. So that should tell you something about its reliability as well as long lasting-ness.
Monochrome means it does not print in colours.
