The printer also has a device called a fuser (minimum two heating rollers), which is responsible for fixing the toner particles on the sheet with the generated heat at the level of about 200 degrees Celsius. The process described above takes place in monochrome laser printers. As for the color, photosensitive drum is irradiated one after the other and subsequent colors are printed one by one (hence the above-mentioned 4 toners with a set of basic colors, the so-called CMYK - cyan, magenta, yellow, black). The first laser printer launched in 1977 was the Xerox 9700 by Xerox, founded in 1906 in Norwalk. It was this company that was the first to start selling photocopiers in 1959.
It is also worth mentioning that in the 1970s a research center called Xerox PARC was created, where, for example, Ethernet or Xerox Alto were built - the first personal computer in the world with a graphic interface that supports, among others image manipulation service laser printers or a computer mouse with three buttons. The dimensions of the Xerox 9700 were considerable as it could fit the entire room. And despite the fact that its capabilities were not impressive for today's times, then it was amazing - it printed 120 pages per minute, each in 300 dpi resolution, had the option of double-sided printing, and also printed in one color. Another laser printer was a printer constructed by Hawlett-Packard, called the LaserJet Classic and cost about $ 3,500. It was dedicated to personal computers appearing on the market more and more boldly.
It had 128 kB memory, also had a resolution of 300 dpi, and was connected to a computer via the RS 232 C interface. The demand for this type of printers was also increased by other companies, including Canon, by releasing their models. when QMS, a company founded in 1977 by Jim Busby, produced the first such device. Today, laser printers, both monochrome and color, are very popular devices that can be obtained at reasonable prices.

Even the smallest projects have their internet representation in the form of a website.
