Dot Matrix Printer - this printer is the cheapest but loudest of the printers. The printer uses a fine stripe of carbon and depending on what pin it is, will determine the quality of the printing. The pin sizes range from 9-24. The printhead hits the ink ribbon with one of its many pins causing it to form a letter number or charature. With the pins hitting the ribbon this printer becomes quite loud. The ppm (page per minute ranges from 1 to 3 but in new changes in technology its is becoming more and more used in offices today and also can print 3 - 6 ppm plus it is much more quiter. The drawback in most dot matrix printers is the on-roll paper which has a track which feeds it through the printer. Also in most new dot matrix printers there is a paper feed which allows most forms of paper.

ports

Ink Jet Printer - This printer is set at the standard for home use. The print head sprays ink onto paper forming an image or text. With imagery on the ink jet it is lost by premature smearing if tuoched prematurally or if the wrong paper was used. The paper best used for imagry is a high clay content paper and for the ink a smudge resistince or oil based ink. For buisnes letters a ink jest printer is the most common one used for its text plus imagry to add to the paper. The common speed on a ink jet printer is about 3 ppm and 300 dpi (dots per inch).

laser

Laser Printer - This printer is used for high speed text printing and rough draft image quality, this orinter is ideal for rough draft or proofing work. This is the most complicated of all printers because of its printing ability, Thus making this printer more exspensvie than the others on the market. This printer has its own iterpritation language called PCL (printer control language). The laser printer works simularly to a photocopier by sending a beam or a laser of positive electrons to the paper, when passed to the ink or toner it becomes attracted (remember oppisites attract) causing it to stick to the paper then passed through to a hot presser which causes the ink to be permenintly enscribed on the paper. This printer print ne where from 4 - 12 ppm.

Post Script Laser Printer - This printer has more option than a PCL printer when you are using different color because of its professional quality. This printer is espeacially used in graphic arts studios.

Color Laser Printer - Is more expensive than a color ink jet printer because it produces a great quality picture.

Thermal-Wax Printer - A thermal wax printe pruduces sharp,rich colors non-smearing colors. This printer uses 3-4 full page color ribons of wax. A heated print head melts the wax and places it on speacilly coated hat sensitive paper. The dpi on this monitor is 300 to 600. This printer is used in high quality imagry and color overhead transparencies.

Dye Sublimation Color Printer (or) (Thermal dye printer) - is the highest quality graphic producing printer there is. this printer uses heat to transfer the ink from colored ribbons into a gas which turns into a glass like substince. This printer has such good graphics it is said to be photographic quality.

The print buffer - can send data faster than a printer can accept and the process the daa/ A print spooler or print buffer axts like a dam, holding the data and then releasing it at a speed the printer can handle.
