Printer printing method

Divided into two types of laser printers and inkjet printing.
Laser printing: The use of a laser beam to quickly "project" a digitized image or document onto a photosensitive surface (photosensitive drum). Electronic charging occurs at the location hit by the laser beam. Then, like a magnet, it attracts some fine iron particles called "toner." For monochrome printers, these toners are black, while for color printers they are cyan, magenta, yellow, and black. The toner is transferred from the photoconductor to the paper. At the same time, because the paper surface passes through a hot roller, the toner is “fixed” to the paper. All these steps can be completed within seconds - except for the printed image, which is almost comparable to a normal copying machine. Most laser printers can use ordinary, inexpensive copy paper, effectively reducing costs. The output quality of laser printers is very high, especially those of the word "Line art", which truly achieves "What You See Is What You Get".

Inkjet printing: Jet fine black or colored ink droplets onto the paper. By using more nozzles and ejecting the same area multiple times, most inkjet printers can output medium, high-resolution images. The inkjet printer may be able to spray cold or hot ink (hot dry faster) or heat the wax pigment (solid ink) until it is liquefied and then ejected, depending on the specific manufacturer and printer model. Due to its low cost, ease of use, and high speed, inkjet printers have become one of the most popular printers today, and many have entered the home. However, in the field of professional printing, people prefer other printing technologies. This is due to the fact that ink jet printing has not been well solved in a long time: the printing result cannot be durable. Most ink-jet printers use pigments that degrade quickly, causing color migration, fading, and eventually deteriorating image quality.
