Hello everyone, welcome to watch, I really don't know. The threshold for entrepreneurship has been low in recent years, and many of the small partners around have started to start businesses. Then, as an essential equipment for office, how to choose a printer? Recently, a business friend asked me if he wants to buy a printer for the company, but he is entangled in buying inkjets or buying laser printers. Today we will discuss this issue from many aspects. Let's take a look at the working principle of inkjet printers and laser printers: inkjet printers first produce small ink droplets, and then use inkjet heads to guide fine ink droplets to a set position, which has the late cost of ink. The laser printer generates a laser beam carrying character information by a laser scanning system. Finally, the laser beam is imaged and transferred to the paper by an electrophotographic system. Its core component is a toner cartridge, and the consumables that need to be replaced later are mainly toner cartridges. For entrepreneurial friends, he needs to choose an affordable printer, printing costs are particularly important. From the point of view of the price of consumables, the toner cartridges on the market are more expensive than ink. However, the theoretical number of printed pages of traditional inkjet printers (5% coverage of A4 paper) is generally 200-300 pages, while the number of theoretical pages printed by laser printers is generally around 2000 pages, so laser printers have an absolute advantage in printing costs. For the current ink cartridge type inkjet printer, its theoretical printed page number has been increased to about 6,000 pages, and the printing cost can be much lower than that of a laser printer. In addition, power consumption is also a very important factor. If the printer is used frequently, the monthly electricity bill is also a small expense. So who is more energy efficient with inkjet and laser? In fact, it can be found in daily use that the power consumption of the laser printer is relatively high. The most obvious performance is that the paper after laser printing is somewhat hot, and the paper printed by the inkjet is relatively cool. This is because laser printers need to heat the drum to image transfer, while inkjet printers spray ink directly onto the paper without heating. In addition to paying attention to printing costs, the health risks of printers can not be ignored. We tested the ozone release of both printers in a closed environment. It can be seen that the air pollution generated by the laser printer is significant compared to inkjet printers. This is because a large amount of ozone and particles are released during laser printing, which may harm the body if it is not well ventilated. It is best for enterprise users to place the laser printer far away from the human body. That is, if the room size is too small, the ventilation is poor, and there are often printing needs, it is best not to use a laser printer. Of course, whether laser printing is environmentally friendly or not depends on the quality of the toner cartridge used. From the above experiments, laser printers consume more power than inkjet printers and generate ozone. Is it not suitable for purchase? In fact, many large companies are using black and white laser printers, because laser printers are a full-page direct output. Compared with inkjet printers, laser printers not only print fine text, but also print faster. The advantage is more obvious. Therefore, the laser printer is more suitable for users who have a large space and a large demand for black and white documents. And if you have color printing needs, especially if you need to print photos, it's obviously more sensible to choose an inkjet printer, and it's smaller and more space-saving. In terms of selling price, the entry price of inkjet printers is relatively low. Now, less than one thousand yuan can buy color inkjet printers, and color laser printers are basically two to three thousand to ten thousand yuan. However, inkjet printers also have a significant disadvantage. Their nozzles are in contact with air. When not printing, ink is also consumed. If it is not used for a long time, the ink may dry out and cause damage to the nozzle. Laser printers It can be used for a long time, and generally there is no such loss. Finally, let's talk about a problem that everyone may have overlooked. The quality of the print is not only related to the printer. Ink, paper, software, original image and other factors will also affect the printing effect, especially paper. At present, the mainstream printers on the market can basically meet the daily needs of ordinary users. Since they all pay for the printer, don't forget to match it with the appropriate printing paper. Ok, this issue of "I really don't know" is here. If you have any topic to discuss with us, please leave a message in the thread. Goodbye to our next show, bye~
