Toner-based printers work by the Xerographic principle that is used in most photocopiers: by adhering toner to a light-sensitive print drum, then using still electricity to move the toner to the printing medium to which it is compound with heat and pressure.
The most ordinary type of toner-based printer is the laser printer, which uses accuracy lasers to reason toner adherence. Laser printers are known for high excellence prints, good print speed, and a low (Black and White) cost-per-copy. They are the most common printer for many general-purpose office applications, but are much less common as consumer printers due to their high first cost - though this cost is dropping.
Laser printers are obtainable in both color and monochrome varieties.
Another toner based printer is the LED printer which uses an array of LEDs in its place of a laser to cause toner bond to the turn out drum.
Recent research has also indicated that Laser printers emit potentially dangerous ultrafine particles, possibly causing health problems associated with respiration and reason pollution equal to cigarettes. The degree of particle emissions varies with age, model and design of each printer but is usually proportional to the amount of toner required. Furthermore, a well ventilated workspace would allow such ultrafine particles to scatter thus reducing the health side effect
