Printer Types

Dot Matrix Printer This type of printer prints out little dots that can form graphics or characters. This type of printer was popular a while back because the only other choice was a daisy-wheel printer that didn't print any graphics. These printers are generally loud, producing a high-pitched buzzing sound, and they don't produce very good graphics. You'll still find them in bank machines and cash registers, but most users don't want anything to do with them. Daisy Wheel printer A printer that uses a wheel with all the characters on it to produce output. The wheel spins, and makes an imprint, then spins to go to the next character. It sounds like a little machine gun. These printers generally aren't used much any more due to the decreased cost of other printers that can produce graphics as well as text. The one good thing about a daisy-wheel printer is that the text is generally very crisp. InkJet printer Inkjet printing is a printing process in which images are formed by the precise placement of really small (picoliter-sixed) droplets of ink fired at high speeds from the nozzles of computer-controlled printheads. Droplets of cyan, magenta, yellow and black ink are combined to form precisely placed dots of various colors, which when viewed from a distance, compose an image. Inkjet Specialty Paper First of all, Inkjet Specialty Papers are the smooth surfaced papers whose a specially formulated coating makes an ideal platform to absorb and to fix the inks that are jetted from the inkjet printer for high quality, full color printing. Throughout the course of ink-jet development, ink chemists and media engineers realized that when a liquid ink droplet contacts the surface of paper, it tends to spread along paper fiber lines as well as penetrate into paper sizing and voids. The spreading of ink droplets is often too excessive and too irregular to maintain the resolution required. The penetration of ink into the paper is often too slow to absorb multiple ink drops on the same spot within very short time intervals. The poor color image quality due to ink spreading and intercolor bleeding is recognized as the critical issue in the development of ink-jet technology. To obtain a high-quality color ink-jet image, the surface of the media requires a special coating. And this's why many vendors offer customers High Quality Inkjet Papers and have a know-how in Inkjet technology by leading the consumable market with professional chemistry. By the way, the special ink-jet-coated media must balance between many design parameters such as drop volume, evaporation rate, penetration rate, coating thickness, etc. Today, because of the popularity of color ink-jet printers, the markets demand for better media such as ink-jet glossy and photo media is more significant. |
