Toner cartridges are designed for use in high-capacity printers & are used mainly in busy offices. The Lexmark 74C2HC0 toner is used as part of a set along with other colours to produce finest top quality laser printing, & thanks to the high capacity of 12, 000 pages on average, they do not have to be changed every few weeks like some other cartridges. Cartridges such as these can be very expensive to buy, & for this reason, it makes sense to seek out the cheapest possible option & ensure that you get the right quality of print & capacity.
