Standard yield or XL, chosen by print volume
The TN-248BK is the standard-yield cartridge, rated by the manufacturer at 1000 pages. The same printers also take the TN-248XLBK, rated at 3000 pages. If you print the odd document now and then, the standard cartridge is enough; at higher volumes the XL version cuts down the number of swaps. The real page count depends on how full the pages are.
