— cartridges for laser printers. This technology is considered optimal for printing documents, in particular business documents: the quality of the black-and-white print is very high, and the cost of printing per sheet is low. However, the cartridges of this type are quite expensive. This is due both to high capacity and long resource, and to the fact that the photoconductor used in printing is usually an integral part of the cartridge, not the printer. It is also worth noting that most of these cartridges are black and white, because the laser technology is rarely used in colour printing.
