Laser Printer Technology Explained

Once a print job is sent the drum gets a positive static charge.

Laser printer technology explained. Sharing documents through digital clouds and mobile applications might be the latest technology trend yet many offices still rely on a good old fashioned printing to share work and get things done. They both use static electricity applied to a drum which helps to apply toner and heat to create an image. The major printer technologies on the market today are inkjet laser and led which are very similar and solid ink. Each technology has its own strengths and weaknesses.

And as versatile as lasers are there are other important components inside like the drum and the toner. Instead as paper passes through the printer the laser beam fires at the surface of a cylindrical drum called a photoreceptor. The cylindrical drum is coated with a photosensitive chemical. The more dots you can squeeze into a square inch the sharper the resulting image is.

Though contrary to popular belief the laser does not actually burn the images onto the paper. Laser printing is an electrostatic digital printing process. In fact there is very little difference between the two when it comes to the basic science of how the two types work. How laser printers work.

Laser printers are similar to photocopiers. Comments off on the difference between inkjet laser and digital printers explained. It produces high quality text and graphics and moderate quality photographs by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a drum to define a differentially charged image. Ink sticks to a laser printer s drum the way this balloon sticks to my pullover.

Laser printers and led printers are often grouped together when speaking in broad categories and for good reason. Printers print by applying ink or toner onto the paper. The drum then selectively collects electrically charged powdered ink and transfers the image to paper which. Inkjets use nozzles that spray tiny drops of ink while laser printers melt dots of toner against the paper.

Printer dpi is dots per inch. Indeed as we describe later in this article the first laser printers were actually built from modified. A laser printer is a printer that uses a focused beam or light to transfer text and images onto paper. The difference between inkjet laser and digital printers explained.

Snapshot printers might also use less common technologies such as dye. These days you can purchase a basic laser or inkjet printer for almost the same price. As the name suggests a laser printer uses lasers for the printing job.
