The following are some understandings of several brands.
1, Canon: Canon made the world's first inkjet printer. Although Canon now lags behind HP in market share, Canon has more patented technologies than HP. Canon's ink drop adjustment technology is an innovation of Canon's ink jet technology, which can eject two kinds of ink drops of normal size and half size on the same print head and one printing line. This new print head design has two heaters. One heater ejects small ink droplets, or two heaters eject ordinary ink droplets together. The combination of two sizes of ink drops can produce more detailed and higher quality output. Canon's inkjet printer system, especially the print head structure and driving software, makes this fine inkjet mode possible. Although this technology does not improve the overall resolution, it can reduce the graininess of colors and improve the output quality of photos and images. 2. Hewlett-Packard: Hewlett-Packard Company is very popular in China because of its excellent products and services. It also has its own uniqueness in technology. Its patented HP photo gray enhancement technology is a big impact on the traditional DPI technology. On this basis, HP developed the "photo II" technology and the second generation of intelligent color enhancement technology (ColorSmartII). The second generation of color gradation enhancement technology is to let the nozzle spray tiny ink drops of 10PL, which is impossible for the naked eye to see. Because such small ink droplets can produce more changes in each pixel, reflecting the changes of hundreds of color levels, thus obtaining satisfactory printing results on ordinary paper. The second generation of intelligent color enhancement technology is that users can easily print the best results on various printing media without worrying about adjusting various printing parameters, which is more convenient when printing a file containing images, charts, color text and black and white text at the same time. 3. Epson: While Canon and Hewlett-Packard are proud of thermal inkjet technology, Epson developed more advanced micro-piezoelectric technology, and later introduced micro-piezoelectric inkjet printing technology and PPIS (Perfect Imaging System) technology on the basis of micro-piezoelectric technology. Miniature piezoelectric print head technology uses the characteristic that crystals vibrate at a stable frequency when energized. By changing the voltage and adjusting the frequency of crystal vibration, the size and ejection speed of ink droplets are accurately controlled. The ink ejected by this technology is only 1/3, which makes the shape of ink drops more regular and accurate and improves the resolution. This result realizes the coexistence of high-quality printing and high-speed printing, and has the advantages of reducing ink consumption and printing cost. 4.Lexmark: Lexmark's products are not familiar to the vast number of users in China, which may be related to its late entry into the China market, but its international status is still very high. Lexmark is a subsidiary of the blue giant IBM, so it can compete with the above three companies in technology and products. Lexmark's patent is excimer laser cutting print head technology. Through this technology, the ink-jet hole and the pressurized cavity of ink to the nozzle can be integrated, so that the diameter of the nozzle is only one micron, so the pattern printed under this nozzle has very ideal effect. Lexmark also developed waterproof ink. Using this ink and high-resolution inkjet printer, the printing effect can be completely comparable to that of laser printing equipment.

But personally, HP is better. He is more popular in China, but he certainly has his advantages.
