Printing back then was characterized by inked wooden blocks or other strong objects pressed firmly on paper. This was specifically apparent with the first printers or presses in history, such as the woodblock printing system of the Han Dynasty. Today, many printers hardly touch the paper.
This is the case with modern-day printing devices such as the laser printer, a gadget so complex that it requires more than an illustration to make it straightforward for average individuals. Gary Starkweather introduced the principle of laser printing in 1969 at a Xerox research facility in New York. However, IBM was the first to produce and market a laser printer with the IBM 3800 in 1979. After a while, other business like Hewlett-Packard (HP) and Apple came up withd their very own laser printing devices.
Laser printers print dry, which means they don't use ink to print characters of various colors into the paper, but a powdery substance called a toner. The workings of a laser printing device make good use of a toner, which is a blend of polymers and color. The biggest advantage of this system is that the toner sticks to the paper more immediately and better than liquid ink.
The laser, toner from the laser printer cartridge, and charges from a corona wire come together in a drum called the photoreceptor drum assembly. However, the toner still won’t stick to the paper just yet; bonding the toner to the paper is the role of the fuser. The fuser is a component that exposes the toner to high heat, creating the polymer to melt, and the pigment to adhere to the paper.
As lasers are known for their accuracy, you can get clear results from laser printing devices most of the time. The printer draws its toners from laser printer cartridges, usually fashioned like a lengthy rectangular container. While toner may be a bit more costly than ink, images printed by laser generally last longer than those printed in liquid ink. Even with ink-based printers taking up majority the industry, there is still a demand for these toner-based laser printing devices.
