What is Printer?

Line Printer, Drum Printer, Daisy Wheel Printer, Dot matrix printer.

                                                                     Impact Printer

                                Line printers are that type of printer which prints one line at a time.

                                                                    Line Printer.

                                                 Printer wheel line on the wheel and pains corresponding to characters which resemble daisy flowed these printers are used for word processing in offices that required a few letters to be printed in good quality. It is more reliable and flexible to change the character set.

                                                          Daisy wheel Printer.

                                               A dot matrix printer is the most popular impact printer it prints one character at a time the print head content vertical array of prints the print head moves across the paper, selected prints fire against a ribbon of ink to form a parallel of the dot on the paper.

                                                                    Dot-Matrix Printer.

 In this printer there is no mechanical contact between the print head and a paper.

                                                             Non-Impact Printer.

Inkjet Printer direct high-velocity steel of ink to words the paper. This steam is reflected bypassing to the electrostatic field or altar-sonic field.

                                     These printers work on the similar mechanisms of a photocopy machine the desired output is written on drum with the help of light beam control by computer with this certain parts of drum gets electrically charged, then this surface is exposed to the laser printer. This laser exposed areal attract tones that form of the image by attaching ink to laser charges. The tones are permanently fused all the paper with heat or pressure.
