Several major brands of laser printers have their own points of purchase, and their quality is also good. In actual purchase, we need to consider the actual situation comprehensively. The laser printer can be purchased mainly from the following aspects: 1. The printing resolution is the same as that of products such as displays. The printer also has a resolution problem. The higher the resolution, the higher the image accuracy and the better the print quality. Therefore, we should try our best to choose printers with higher resolution. At present, the resolution of mainstream black and white laser printers mainly includes 600dpi × 600dpi, 1200dpi × 600dpi, 2400dpi × 600dpi, 1200dpi × 1200dpi, 2400dpi × 1200dpi, etc. The higher the resolution, the more expensive the product price. General users can choose 600dpi × 600dpi products, and users with high requirements can choose 1200dpi × 1200dpi products. 2. Printing speed Printing speed is also an important parameter that affects the working quality of a printer. The printing speed of a printer refers to how many pages (PPM) the printer can print per minute. In addition, when marking the technical indicators of products, manufacturers usually use black and white and color printing speeds. Because the printing speed of the printer is very different when printing images and texts, in addition, the printing speed is directly related to the resolution set when printing. The higher the printing resolution, the slower the printing speed, Therefore, the printer's printing speed must be comprehensively evaluated under the unified standard. At present, the printing speed of mainstream black and white laser printers is generally 10-20 pages per minute, which can meet the needs of general commercial users. 3. Price and consumables Although many people think that ordinary business users seldom consider the purchase price when purchasing a machine, the author does not think so. In contact with many office users, they will not only consider the cost of consumables, but also the purchase price of the complete machine for budget needs.
