1. Laser Printers
Laser printers are devices that use laser technology to print. Their working principle is to scan the laser beam on a photosensitive drum to form a latent electrostatic image, which is then fixed on the paper through the adsorption of ink powder and thermal fixation. Laser printers are known for their fast printing speed, high resolution, and suitability for large printing jobs. Additionally, the ink powder used in laser printers has a longer service life and cost efficiency, making it a preferred choice for corporate users and large offices. 2. Inkjet Printers Inkjet printers are devices that use inkjet technology to print. Their working principle is to spray ink onto the paper through a nozzle to form images or text. Inkjet printers offer high resolution and rich color expression, making them suitable for the printing needs of home users and small offices. Furthermore, inkjet printers are easy to operate and relatively low in price, making them popular with users. However, inkjet printers are relatively slow in printing speed and the cost of ink is high, requiring regular replacement of print heads and ink cartridges. 3. Multifunctional All-in-One Machines Multifunctional all-in-one machines are devices that integrate printing, copying, scanning, and faxing functions into one device. These printers not only have the functions of laser printers and inkjet printers, but also have higher efficiency and convenience. Multifunctional all-in-one machines usually have high printing speed and resolution, which can meet various office needs. Additionally, their integrated multi-functions can save space and improve work efficiency. However, multifunctional all-in-one machines are relatively expensive and should be selected based on actual needs.
