Laser Printer Technology Explained

How laser printers work.

Laser printer technology explained. A laser printer is a printer that uses a focused beam or light to transfer text and images onto paper. These days you can purchase a basic laser or inkjet printer for almost the same price. In fact there is very little difference between the two when it comes to the basic science of how the two types work. The cylindrical drum is coated with a photosensitive chemical.

Both inkjet and laser printers are appropriate for meeting different printing needs. The drum then selectively collects electrically charged powdered ink and transfers the image to paper which. And as versatile as lasers are there are other important components inside like the drum and the toner. Ink sticks to a laser printer s drum the way this balloon sticks to my pullover.

Printers print by applying ink or toner onto the paper. Once a print job is sent the drum gets a positive static charge. Each technology has its own strengths and weaknesses. As the name suggests a laser printer uses lasers for the printing job.

The difference between inkjet laser and digital printers explained. Laser printing is an electrostatic digital printing process. Laser printers are similar to photocopiers. They both use static electricity applied to a drum which helps to apply toner and heat to create an image.

The conversation here is not as simple as which is best. 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. The more dots you can squeeze into a square inch the sharper the resulting image is. Inkjets use nozzles that spray tiny drops of ink while laser printers melt dots of toner against the paper.

Snapshot printers might also use less common technologies such as dye. Though contrary to popular belief the laser does not actually burn the images onto the paper. Printer dpi is dots per inch. Comments off on the difference between inkjet laser and digital printers explained.

Laser printers are a lot like photocopiers and use the same basic technology. Laser printers and led printers are often grouped together when speaking in broad categories and for good reason. 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.
