Laser Printer VS Inkjet Printer

The printer, the choice of laser or inkjet? It is a topic of discussion, and the time is different. The conclusions may be different, but at any time, it is considered from the point of view of applying the life cycle cost, that is, it must be from the purchase cost, the use cost, the product life, the disposal Cost, environmental protection and many other aspects measure the rationality of their choices. In addition, in view of the fact that dot printers and thermal printers are relatively small in use at the current stage and their use is relatively single, only laser printers and inkjet printers are discussed in this paper.
First, it briefly introduces the working principle of laser printers and inkjet printers. The principle of laser printers is to use laser scanning imaging technology to charge the imaging drum with static electricity to attract the toner. The heating roller heats the paper to melt the toner into the paper. Complete the thermal imaging print process. The principle of the inkjet printer is to control the print head dot jet printing ink through a digital circuit to complete the printing process. The main consumables for laser printers are laser, and the supplies for inkjet printers are print cartridges and printheads.
Second, discuss the main basis for choosing a printer, or how to determine the appropriate printer to use. The author believes that from the perspective of use to determine whether a printer is selected according to the main criteria are: print speed, print quality (quality), printing costs, print format, the convenience of replacing printing supplies and whether environmental protection and other factors. The printer print speed is generally calculated in terms of the number of pages printed per minute (PPM), according to the print output speed can generally be divided into three categories: low-speed printer (10 ~ 30 PPM); medium-speed printer (40 ~ 120 PPM); high-speed printer (130 to 300 PPM). Many years ago, inkjet printers only had a place in the low-speed printing field. It is also not suitable for ink jet printers in areas where the monthly print load requires thousands of pages or tens of thousands of pages. In addition, laser printers can achieve automatic two-sided printing, whereas inkjet printers originally required manual methods for two-sided printing.
Finally, talk about technology and talk about current inkjet printers. Compared to laser printers, the general impression people have on inkjet printers is that they are cheap, they have slow print speeds, they have poor print quality, they are easy to dry, and they are easy to clog. A few years ago, this view was undoubtedly correct. However, since 2005, especially after 2009, after adopting a series of new technology inkjet printers to market, this view is no longer correct.
For example, some companies have adopted new precision micro-piezoelectric technology to completely solve the problem of blockage of printer nozzles that plague the industry through bubble elimination system and volatility suppression system; precise control of paper motion technology is used to ensure reliable print quality and operation and achieve double Surface printing; automatic ink jet health checks, active and passive inkjet head replacement, active printhead maintenance technology ensure print quality; printheads made with scalable printing technology, due to the use of extremely precise and reliable materials, design Rules and manufacturing processes have greatly improved the reliability and stability of the print head. Consumables problems have always been a major problem for printers, but now some companies, in addition to configuring high-volume ink cartridges, also use pigmented inks to achieve high-quality printouts, and to prevent fading, waterproofing, and prevent highlighter smearing. Print quality does not change for decades. This output quality is ideal for printing text that requires long periods of time.
The ink jet printer adopting new technologies has exceeded the three major bottlenecks of cost, speed and quality, and has surpassed traditional laser printers in terms of durability, environmental protection, and cost. In particular, the new generation of inkjet printers has low power consumption. The features of low energy consumption and low cost are more in line with the government's requirements for building a resource-saving, environment-friendly society and meeting the requirements of ecological civilization construction.
The author believes that inkjet printers have a tendency to replace laser printers in terms of life cycle cost. Of course, it is not ruled out that after several years, with the improvement of the laser printer technology, it will once again become the darling of the market. It may be a true portrayal of this status quo that the leaders are three or five years old. This is the credit for technological progress.
