General principles of printer failures
Whether working from home or working from office, a printer is definitely a necessary office product. Using printers, we can perform home office text output, multimedia production effect output, image print output, and other media output. Different application fields will have different requirements for the printer's usage requirements and printing effects, and at the same time, certain requirements are put forward for the printer's own performance. When everyone uses a printer, they also hope that the printer can bring convenience and speed to themselves. However, many beginners often encounter various printing failures during the process of using the printer, which brings great trouble to their normal work. Will the vitality of the printer be so "fragile"? No, in fact, many faults are caused by the operator's lack of knowledge about the printer; in addition, not understanding the printer knowledge will also prevent us from choosing a printer with fast printing speed, low usage cost and strong operability among the dazzling printer products! To this end, this article will introduce the relevant knowledge of the printer in detail, hoping to let users truly enjoy the wonderfulness brought to us by the good printer!
1. The development history and market status of printers
According to the output effect, printers are mainly divided into laser printers, inkjet printers, needle printers and other special function printers; for many ordinary users, there are not many opportunities to use needle printers and other special function printers, so this article will focus on introducing laser printers and inkjet printers to you.
Laser printing technology first appeared in the 1960s, and the real investment was actually applied in the early 1970s. The laser emitter in the earliest laser printers was an electronic laser tube filled with helium-neon gas, which was large in size, so it was subject to many restrictions in actual application. With the continuous emergence of high-sensitivity photosensitive materials and the continuous development of laser control technology, laser printing technology has matured rapidly and has been put into practical applications. Technical personnel represented by the United States have successively designed semiconductor laser printers based on the technology of electrostatic copiers, combined with laser technology and computer technology. Compared with needle injection, this printer is not only of good quality, fast output speed, but also has no noise, so it has been quickly promoted and applied. After entering the 1990s, the output processing speed of laser printers has reached 8 pages per minute, and the printing accuracy is 600DPI. It is worth mentioning that HP's resolution enhancement technology and PCL printer language technology have become the general standard for laser printers at this time.
Currently, laser printers can be divided into low-speed laser printers (10 to 30 pages per minute output), medium-speed laser printers (40 to 120 pages per minute output) and high-speed laser printers (130 to 300 pages per minute output). Currently, in the laser printer market, relatively famous brands include HP, Epson, Canon, Lexmark, Ricoh, Panasonic, Xerox and other series. Recently, my country's Lenovo and Founder brand laser printers have also occupied a certain market share.
Inkjet printers only appeared in the early 1990s. They changed the defect of the monotonous color output of traditional needle printers and brought users into a colorful printing world. However, since the spraying technology was not yet fully mature when it was first launched, the cost of various designs and development was relatively high. At that time, inkjet printers were only used in some professional printing systems or advertising design industries. With the continuous maturity and innovation of inkjet printing technology, the application scope of inkjet printers is also expanding. In addition to being used in normal business offices and personal offices, the "figure" of inkjet printers has begun to appear in desktop printing systems, advertising design systems, printing and publishing systems, and photography and painting systems. Now that inkjet printing technology is becoming more and more mature, its various design costs are also declining significantly, which makes it possible to quickly popularize inkjet printers among individual home users.
In recent years, with the continuous increase in the number of home computer users, inkjet printers are gradually becoming the first choice for individual users due to their price advantages and good printing results. The current inkjet printers have also developed from the initial rough effect, slow output and long time to the current photo-level effect, fast output and easy operation. In particular, the latest inkjet printers integrate digital functions. This type of printer is very interesting and can print out various very interesting home digital image effects according to the different requirements of the printer users.
2. Working principle
After understanding the development process of printers and the current situation, do you know how printers work? Let’s take a look at the working principle of laser printers and inkjet printers!
