The principle of work of a laser printer is similar to a copier. First, the paper creates a magnetized area that attracts print powder (toner). Then a sheet of paper falls into the “oven” where the powder melts. Subsequently, the powder is cooled and solidified as a result.
Laser printers of the initial price level, allow you to get only black and white copies, but of high quality and very fast. In recent years, laser printers are enjoying increasing popularity, which is led by quite good reasons:
1. Sharp decrease of prices for laser printers.
2. Colour laser printing has become cheaper and better. They are quickly repaid, due to a large number of imprints.
3. Extremely high quality of imprints, especially for texts and business graphics, printed with laser printers.
4. Laser printers, compared with their counterparts of other types, are simple to maintain, more reliable and economical. For example, one cartridge refill for laser printer allows you to print from 2,5 to 10 thousand copies, and the average resource of its drum ranges from 10 to 60 thousand impressions depending on the model.
5. Laser printers print quickly and quietly, which is very important for work in the office.
