Hewlett-Packard is a well-known "garage startup" company, which originated in the thirties of the last century and is considered the emblematic pioneer of Silicon Valley. In addition to the PC business, which is the world's largest market share, printers have always been HP's traditional strength, and with the acquisition of Samsung's printer business in 2016, HP further expanded its footprint.
 
Unlike Epson and Canon, HP is firmly on the road to commercial printers, and most of its civilian products are all-in-one machines, and the text printing ability is very good. But since cutting its Photosmart series, HP has essentially abandoned the 6-color inkjet printer for photos. Even the Envy series, which is currently dominated by photo printing, only has four-color ink cartridges. Although the four-color printer can also be used for photo printing, it is troublesome to maintain and the color gamut is not wide enough, which is still more than a gain for users who need pure photos.
 
HP Sprocket Series Zink printers have gained a lot of attention. Due to the similarity of Zink printer technology, the HP Zink printer is really not much different from LG, and the HP small print color is slightly yellowish in the details, which is a good and bad feature. In some portraits and landscapes, the photos typed by HP Xiaoyin are like their own filters, and they are more stylish. But in some low-contrast photos, the photos typed by HP will have a gray feeling. While the first and second Sprocket 100 and Sprocket 200 photos are only 2x3 inches (5x7.6cm), the new Sprocket Plus photo size has been increased to 5.8x8.6cm, making them slightly more content-rich photos. At present, the price of several HP small prints is about 800 yuan, but the price of Plus photo paper is slightly more expensive, about 4 yuan per sheet. The first two generations of photo paper are 2~3 yuan.
