Why is everyone paying so much attention to the ranking of printers? In the spring of each year, it will enter the peak sales season for inkjet printers, and some production and processing enterprises will begin to highlight the demand for marking equipment. As an unpopular industry, many people have never heard the name of this equipment. How to quickly understand the industry and understand the equipment situation, rankings can be said to be a very popular concept on the Internet. Is the ranking list of inkjet printers circulating on the Internet reliable? An authoritative and credible brand ranking can help everyone have a quick and overall understanding of the entire industry. Especially for some new customers (users who want to buy inkjet printers) to provide some technical support and help, quickly understand the brand models existing in the entire industry, and filter out the types of equipment that suit their product conditions and marking needs. However, in China, as of 2018, there is no authoritative statistical agency that can make an objective and fair evaluation and ranking of many brands and many manufacturers at home and abroad. More subjective comparisons, reviews, brand promotion, product introductions and other information of some suppliers are not very accurate and cannot quickly provide users with one-stop problem solving and get a valuable answer. How to form an objective, fair, and reference-value inkjet printer ranking list? Big data is very popular. Through big data, we can carry out multi-dimensional statistics, such as printer type, printer sales, printer failure rate, printer price, printer damage, printer maintenance, etc. Aspect data. Only by conducting statistical analysis of data, conducting objective and fair comparisons from more dimensions, and discovering the differences and pros and cons between brands, can we achieve a ranking list with real reference value and significance. Allow users to obtain truly valuable reference information through the list, be well-informed when purchasing or choosing, and have a certain basic understanding of some common brands, models, performance, advantages, and characteristics. Example analysis: First, there must be a segmented brand category, which cannot be collectively referred to, such as handheld inkjet printers. Then, there must be cross-evaluations of some brands with a higher market share, and detailed, specific, fair and objective evaluations and comparisons in terms of hardware and software. Secondly, there must be a detailed description of the price, what configuration (function) price ratio. Finally, there must be some word-of-mouth feedback, similar to Taobao and Tmall, with user experience and real feedback after purchase and use. In this way, we can better see the quality of a brand, a type, and a model of inkjet printers, especially what problems, advantages and disadvantages will be encountered in actual use, can be seen intuitively. Why is everyone concerned about the ranking of printers? This is a bit complicated to analyze. First, we must split it from the people who are concerned, including printer manufacturers, agents, system integrators, real customers and other different groups of people. However, there are also a large number of people who are doing brand promotion and printer equipment promotion, so as to write rankings for users to refer to. The actual value generated to users is very limited. If you look at it too much, it will make users feel More confused. Here we can't help but ask, what is the role of the list? What are the core requirements? Of course, real users' needs for understanding of various brands may not account for a large proportion, but it is also the core of supporting this ranking. Of course, there will be a distinction here, such as domestic and imported; such as inkjet and laser. So how do you have to quickly, truthfully and objectively understand the quality of inkjet printers? The first recommendation of Qianli is to suggest customers to conduct on-site inspections, come to the company, come to the factory, take a look at the site, and take a sample to test it on the spot. By looking at the environment, looking at the personnel, looking at the effect, you can have some in-depth understanding of the supplier intuitively and quickly, instead of staying on the website or advertising color pages, in order to better provide purchasing decisions. It is not possible to tell whether a product is good or bad through the ranking list. Shanghai Qianli suggests that you can refer to some inkjet printer evaluation, use actual measurement and other videos, graphic consultation and other information, which will be used in our production work. The coding equipment has more practical reference significance.
