chain printer. An early line printer that used type slugs linked together in a chain as its printing mechanism. The chain spins horizontally around a set of hammers. When the desired character is in front of the selected print column, the corresponding hammer hits the paper into the ribbon and onto the character in the chain.
A daisy-wheel printer works on the same principle as a ball-head typewriter. 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.
Dot matrix printers, also referred to as impact printers, use technology different from laser and ink jet printers, which lets them print information through multiple page, carbon-copy forms in a single pass. Creating an instant copy of data lets you manage billing, shipping, and warehousing areas with efficiency.
Though it doesn't make a nice sound when struck, the laser printer drum is an important part of the band that is a laser printer. It is the metal roller that gets etched with the image of your print job by a laser. As the drum gets charged by a laser, it picks up toner, and then rolls that toner onto a piece of paper.
Dye-sublimation printers allow you to print photo-lab-quality pictures at home. As the price of these printers go down, more and more digital-camera owners are choosing to take advantage of this technology. In dye-sublimation printing, colors are not laid down as individual dots, as is done in inkjet printers. Individual dots can be distinguished at a relatively close distance, making digital pictures look less realistic.
An inkjet printer is a computer peripheral that produces hard copy by spraying ink onto paper. A typical inkjet printer can produce copy with a resolution of at least 300 dots per inch (dpi). Some inkjet printers can make full color hard copies at 600 dpi or more.
The laser printer is different from an inkjet printer in a number of ways. The toner or ink in a laser printer is dry. In an inkjet, it is wet. Over time, an inkjet printer is about ten times more expensive to operate than a laser printer because ink needs replenishing more frequently.
A line printer is an impact printer which makes use of a continuous feed of paper and prints one line of text at a time. Although they have been replaced in most instances by high-speed laser printers, they are still used in some business as they are low cost and have the ability to print on multi-part forms.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper, plastic, or other substrates. Inkjet printers are the most commonly used type of printer, and range from small inexpensive consumer models to expensive professional machines.
A thermal printer is a printer that makes use of heat in order to produce the image on paper. Due to quality of print, speed, and technological advances it has become increasingly popular and is mostly used in airline, banking, entertainment, retail, grocery, and healthcare industries.
Digital printing has come a long way with high definition toner-based technologies offering print on demand high quality data and images on assorted media. Toner is largely powder-based used in laser/digital printers, using organic compounds and polymers to make up the majority of the material.
