All this means that more and more people decide to buy branded toners even when they are slightly more expensive than their substitutes.As a result, they have the certainty that their prints will look almost perfect, and certainly very clearly. Among these accessories, printers can be distinguished by company toners, which allow you to make specialized prints, maintained at the highest level.
Laser printing is an electrostatic digital printing process.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.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both. As with digital photocopiers, laser printers employ a xerographic printing process.
This enables laser printing to copy images more quickly than most photocopiers.Źródło: https://en.wikipedia.org/wiki/Laser_printing.
