By definition, a monochrome printer is a printer that gives you prints of only one colour. A monochrome printer usually prints black while some other monochromes print text and graphics in grey-scale, as well as strictly in black–and–white.
Monochrome printers are employed for extensive and qualitative printing of texts. Monochrome lasers are more efficient than the inkjets in terms of their monthly duty cycles, except for printing photos. Laser monochrome printers offer an output of atleast 600 dpi for smoother gradients, cleaner graphics and sharper edges. A user could go for a higher resolution monochrome laser for printing photos.
Monochrome thermal printers are used in cash registers, ATMs, gasoline dispensers and some older inexpensive fax machines
