Impact and non impact printers

What are Impact and Non-Impact Printers? Memory A printer is an output device that prints characters, symbols, and perhaps graphics on paper. The printed output is generally referred to as hardcopy because it is in relatively permanent form.

Softcopy refers to temporary images such as those displayed on a monitor. Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do not.

Impact printers An impact printer has mechanisms resembling those of a typewriter.

Difference between Impact Printer and Non Impact Printer – Difference Between

It forms characters or images by striking a mechanism such as a print hammer or wheel against an inked ribbon, leaving an image Impact and non impact printers paper. Impact printers are dying out; however, you may still come in contact with a dot-matrix printer.

A dot-matrix printer contains a print head of small pins that strike an inked ribbon, forming characters or images. Print heads are available with 9, 18, or 24 pins; the pin head offers the best print quality.

Dot-matrix printers permit a choice between output of draft quality; a coarser-looking 72 dots per inch vertically, which may be acceptable for drafts of papers and reports, and near-letter-quality, a crisper-looking dots per inch vertically, which is more suitable for a finished product to be shown to other people.

Dot-Matrix Printers Dot-matrix printers print about characters per second cps and can print some graphics, although the reproduction quality is poor.

Color ribbons are available for limited use of color. Dot-matrix printers are noisy, inexpensive, and they can print through multipart forms, creating several copies of a page at the same time, Daisy-Wheel Printer A type of printer that produces letter-quality type.

The daisy wheel is a disk made of plastic or metal on which characters stand out in relief along the outer edge. To print a character, the printer rotates the disk until the desired letter is facing the paper.

Then a hammer strikes the disk, forcing the character to hit an ink ribbon, leaving an impression of the character on the paper. You can change the daisy wheel to print different fonts. Daisy-wheel printers cannot print graphics, and in general they are noisy and slow, printing from 10 to about 75 characters per second.

As the price of laser and ink-jet printers has declined, and the quality of dot-matrix printers has improved, daisy-wheel printers have become obsolete. Drum Printer An impact printer in which a complete set of characters for each print position on a line is on a continuously rotating drum behind an inked ribbon, with paper in front of the ribbon; identical characters are printed simultaneously at all required positions on a line, on the fly, by signal-controlled hammers.

Chain Printer It is the character printer. The print element in a chain printer is a metallic band or chain containing the embossed characters that rotates horizontally in front of paper. A complete chain consists of the five sections; each section consists of 48 characters.

As the print chain rotates, properly timed print hammers strike the paper along with linked ribbon, against the proper character on the chain as it passes.

Chain printer are one of the fastest impact printers that can produce up to to characters per second. Chain Printer also called band printers, contain characters on a rotation band.

Speeds of up to lines a minute may be possible with these machines. Line Printer A high-speed printer capable of printing an entire line at one time.

A fast line printer can print as many as 3, lines per minute.

The disadvantages of line printers are that they cannot print graphics, the print quality is low, and they are very noisy. Other Impact Printer Are 1.

Nonimpact printers form characters and images without direct physical contact between the printing mechanism and the paper. Two types of nonimpact printers often used with microcomputers are laser printers and ink-jet printers. Like a dot-matrix printer, a laser printer creates images with dots.

However, as in a photocopying machine, these images are created on a drum, treated with a magnetically charged ink-like toner powderand then transferred from drum to paper. They produce sharp, crisp images of both text and graphics, providing resolutions from dpi up to dpi, which is near-typeset quality NTQ.

They are quiet and fast. They can print text-only pages per minute for individual microcomputers, and more than pages per minute for mainframes.

Pages with more graphics print more slowly. They can print in many fonts type styles and sizes. The more expensive models can print in different colors.Jul 15,  · Some of these printers use spray ink non impact printer definition is a printing device (such as laser printer) in which element does not directly .
