In the past, printing typically involved stamping a piece of paper with a piece of inked block or hard object. This was quite evident with the first printing devices or presses in history, such as the woodblock printing system of the Han Dynasty. Today, many printers hardly touch the paper.

This holds true with contemporary printers such as the laser printer, a device so complex that it needs more than an illustration to make it straightforward for average users. Gary Starkweather introduced the concept 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. Eventually, other companies like Hewlett-Packard (HP) and Apple came up withd their own laser printers.

Laser printing devices print dry, which means they don't use ink to print characters of various colors into the paper, however a powdery substance called a toner. The workings of a laser printer make good use of a toner, which is a blend of polymers and color. The strongest benefit of this system is that the toner adheres to the paper faster and better ...
... than standard ink.

The laser, toner from the laser printer cartridge, and costs from a corona wire come together in a drum called the photoreceptor drum assembly. Bu, the toner still can’t adhere to the paper just yet; bonding the toner to the paper is the role of the fuser. The fuser is a part that exposes the toner to high temperatures, creating the polymer to melt, and the pigment to stick to the paper.

As lasers are notable for their accuracy, you can expect clear results from laser printing devices most of the time. The printer draws its toners from laser printer cartridges, mostly looking like a slender rectangular container. While toner may be a bit more costly than ink, documents printed by laser typically last longer than those printed in standard ink. Even with ink-based printing devices taking up most of the industry, there remains a demand for these toner-based laser printers.
