How Printers Work

It’s pretty cool to watch something you put together on a screen come to life on a page, and printers can do just that. If you wrote a book then the printers can print it, same if you made a graphic or created a PowerPoint. But how exactly does a printer turn bits of computerized data into a physical imprint?

A laser printer is the key to communication between the electronic data and the physical form of the paper. The laser beam is controlled by the data and that laser gets ink on the page. Going from electricity to ink uses static electricity to transfer the image onto a photoreceptor drum. Once the entire image is placed on the drum, the ink roller comes in and touches the drum and the image sticks to it.

The sheet of paper moves underneath the drum and the image is attached to it before heat fuses the two together and shoves the paper out to you. That’s why the papers coming out of printers are so warm, and it’s also where the phrase hot off the presses comes from. There’s a little more science as to how the printer works, but that’s the basics.

It’s also why printers need lots of ink. Ink and toner delivery San Francisco services will always be in business when a printer needs them! The laser, a few moving parts, and some electrical charges all allow for the on-screen image to become a physical item that you can touch and manipulate. It’s worth knowing how the printer works, even if you aren’t the guy or girl repairing it, simply to marvel at how a little science allows for something great to be created. After all, we use printers every single day, and without them, I don’t know what would happen.
