First of all, it depends on what functions you need. Multifunctional machines are mainly divided into three-in-one and four-in-one For example, Lenovo M7400Pro is a combination of printing, copying and scanning, and M7256WHF has fax function, depending on whether you need it. The second is to choose performance, but also according to your needs. For small and medium-sized companies and office groups, you can choose a printing speed of about 28 pages/minute. If it is for personal use, the printing speed of 20 pages/minute is almost the same, because the printing volume is limited and the performance is difficult to reflect, but the price has gone up. If it is for home use, you may have to choose the appearance. There are still many good-looking printers, so there is no need to choose ugly ones at home. Lenovo Xiao Xin's white machine is very suitable for home use. M7400Pro is more suitable for office with simple appearance. One more thing, if you are obsessed with laser or inkjet, I suggest choosing laser. Although the price of the machine is relatively high, it can save a lot of consumables in the later stage, and there is no small problem of blocking the ink jet port from time to time, so it is more worry-free to use. I hope I can help you.
