World's first computer printer was a 19th-century mechanically driven apparatus invented by Charles Babbage for his difference engine.

WHAT ARE ITS MAJOR TYPES? Major types of printer Printers

can be divided into two main groups, impact printer and non-impact printer.

Impact printer-Impact printer produces text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper.

Non-Impact printer-Non-impact printer produces text and graphics on paper without actually striking the paper.

•Noisy•Limited Print Quality•Low Printing Speed•Limited Color Printing

INK JET PRINTER:

They are non-impact printers which print text and images by spraying tiny droplets of liquid ink onto paper.

They use CYMK color combination for generating all other colors.
