How does a printer work?

There are two main types of printer, a laser printer and an inkjet printer. Broadly speaking, the printers which Print Logic supply and maintain are mostly laser, as they’re the most reliable, cost effective and high-quality devices available for most of our customer’s requirements. More specialist industries like construction and designers need specific printing machines for their sectors, so we also supply wide-format printing solutions to accommodate this. These devices are always a special type of inkjet printer which can produce exceptionally high-quality, large scale prints.

Laser Printer

Laser printers are a lot like photocopiers and use the same basic technology. The first laser printers were actually built from modified photocopiers. In a photocopier, a bright light is used to make an exact copy of a printed page. The light reflects off the page onto a light-sensitive drum; static electricity (the effect that makes a balloon stick to your clothes if you rub it a few times) makes toner particles stick to the drum; and the toner is then transferred to paper and “fused” to its surface by hot rollers.

A laser printer works in almost exactly the same way, with one important difference: because there is no original page to copy, the laser has to write it out from scratch. Instead the printer gets the information on what it needs to print out from the data your computer sends to it when you press the print button on your PC. This data is used to control the printer’s laser, and that laser is how the toner gets onto the page – simple!

Wide-format Printer

Wide format printers are typically used to print posters, banners, construction plans, architectural drawings or even vehicle wraps. Even though the size of the documents produced is significantly greater, the same basic principles of an inkjet print are applied, but in a far more economical manner.
