Laser Printer Technology Explained

Though contrary to popular belief the laser does not actually burn the images onto the paper.

Laser printer technology explained.

Printers print by applying ink or toner onto the paper. As the name suggests a laser printer uses lasers for the printing job. 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.

The major printer technologies on the market today are inkjet laser and led which are very similar and solid ink. The more dots you can squeeze into a square inch the sharper the resulting image is. Laser printers are a lot like photocopiers and use the same basic technology. Once a print job is sent the drum gets a positive static charge.

Both inkjet and laser printers are appropriate for meeting different printing needs. These days you can purchase a basic laser or inkjet printer for almost the same price. The difference between inkjet laser and digital printers explained. Indeed as we describe later in this article the first laser printers were actually built from modified.

The drum then selectively collects electrically charged powdered ink and transfers the image to paper which. Laser printers and led printers are often grouped together when speaking in broad categories and for good reason. They both use static electricity applied to a drum which helps to apply toner and heat to create an image. Laser printing is an electrostatic digital printing process.

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. Inkjets use nozzles that spray tiny drops of ink while laser printers melt dots of toner against the paper. Each technology has its own strengths and weaknesses. The cylindrical drum is coated with a photosensitive chemical.

Instead as paper passes through the printer the laser beam fires at the surface of a cylindrical drum called a photoreceptor. Snapshot printers might also use less common technologies such as dye. And as versatile as lasers are there are other important components inside like the drum and the toner. Laser printers are similar to photocopiers.

The conversation here is not as simple as which is best. Ink sticks to a laser printer s drum the way this balloon sticks to my pullover. In fact there is very little difference between the two when it comes to the basic science of how the two types work.
