from matrix unstressed office hours due to that their

plotting head is a set of not needles, and thin

nozzles the diameters of that make the tenths of millimeter. The first firm making an ink-jet printer is "Hewlett-Packard". The era of domestic printers was begun with 1985

in high-rate enough of printing, but cost expensive.

the laser printing. Light-emitting-diode technology of printing was invented by

a firm Casio. The first light-emitting-diode printer was produced in a sale by a company OKI in 1987, and in 1988 by the same company the first cultured light-emitting-diode printer was produced.
