Laser Printer Technology Explained

Laser printers are a lot like photocopiers and use the same basic technology.

Laser printer technology explained.

These days you can purchase a basic laser or inkjet printer for almost the same price. Printers print by applying ink or toner onto the paper. Indeed as we describe later in this article the first laser printers were actually built from modified. In fact there is very little difference between the two when it comes to the basic science of how the two types work.

Instead as paper passes through the printer the laser beam fires at the surface of a cylindrical drum called a photoreceptor. The conversation here is not as simple as which is best. Inkjets use nozzles that spray tiny drops of ink while laser printers melt dots of toner against the paper. Once a print job is sent the drum gets a positive static charge.

Comments off on the difference between inkjet laser and digital printers explained. The cylindrical drum is coated with a photosensitive chemical. Each technology has its own strengths and weaknesses. Snapshot printers might also use less common technologies such as dye.

The major printer technologies on the market today are inkjet laser and led which are very similar and solid ink. How laser printers work. Though contrary to popular belief the laser does not actually burn the images onto the paper. 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.

Both inkjet and laser printers are appropriate for meeting different printing needs. The difference between inkjet laser and digital printers explained. The drum then selectively collects electrically charged powdered ink and transfers the image to paper which. Laser printers are similar to photocopiers.

A laser printer is a printer that uses a focused beam or light to transfer text and images onto paper. The more dots you can squeeze into a square inch the sharper the resulting image is. Laser printers and led printers are often grouped together when speaking in broad categories and for good reason. Laser printing is an electrostatic digital printing process.

And as versatile as lasers are there are other important components inside like the drum and the toner. As the name suggests a laser printer uses lasers for the printing job. Ink sticks to a laser printer s drum the way this balloon sticks to my pullover.
