• Types of scanners: image scanner, 3D scanner, biometric scanner, barcode scanner.

Graphic output devices

• Dot matrix printers, laser printers, inkjet printers, offset printing machine.

Matrix Printers

• matrix printer is a computer printer that creates an image on paper from individual small dots in an impact manner

Laser printers

• A laser printer is a type of printer that allows you to quickly produce high-quality prints of text and graphics on plain paper. Like photocopiers, laser printers use the xerographic printing process in their work, but the difference is that the image is formed by direct scanning of the photosensitive elements of the printer with a laser beam.

Inkjet printers

• An inkjet printer is a type of printer. It has a slow print speed compared to laser, but it has a high quality half-tone images.

Offset Printing Machine

• OFFSET PRINTING MACHINE - a printing machine with a printing section of three cylinders - printing, plate and transfer offset, covered with an elastic cover, onto which ink is squeezed from the printing elements of the printing plate, fixed on the plate cylinder, and from this cover it is imprinted on the printed material.

digital duplicator

• A digital duplicator is a printing press that uses a screen printing method. Sometimes it is called "risograph", after the name of the company Riso, which specializes in the production of these devices and which became one of the first on the Russian market. The first duplicator was also created by Riso in 1980 in Japan.
