Advantages
The laser printer has the best printing quality compared to all the other printers. Most offices and publishing companies use them, but they are not commonly owned by home users. These printers can print photo quality images as they have very high dots per inch ratio. Their laser beam also comes with an unvarying diameter. This means the printer can draw much more accurately without wasting extra ink. Laser printers also have fairly high speed, especially when printing out images with colour.
