In short, printers work by converting digital images and text into physical copies. They do this using a driver or specialised software that has been designed to convert the file into a language that the printer can understand. The image or text is then recreated on to the page using a series of miniscule dots.

How do printers print?

When the paper moves near the photoreceptor drum, it attracts the toner, which has a negative charge. The toner is attracted to it and sticks to the paper. The heat and pressure from the rollers fuse the toner particles permanently into the fiber of the paper. That is how a printer prints a piece of paper.

What is the science behind printer?

Thermal print heads use the science of heat and expansion to create a bubble within the inkjet cartridge to push ink droplets out in the form of the chosen print. As the ink heats, a bubble forms and when the bubble reaches a pressure too high to contain, the ink droplet is forced through the nozzle and onto the page.

How does laser printer work?

How a laser printer works. They work by using a heated wire to positively charge a drum, which is then passed over by a laser that reverses the charge in the areas that it hits. A toner roller is passed over the drum, and toner particles stick to the negatively charged areas.
