Laser printer Brother 7030 Samsung 4321 HP 1136 Fuji Xerox 3119

For students to print materials and make copies, I personally recommend Brother’s machine. Why? Let’s look at other things first. Samsung and Xerox actually belong to the same company (A4 machines). If they add powder, they all use the same kind of powder. They come from the same source. The life of the drum core is about the same, about 4,000-5,000. In addition, on rainy days, the paper jam phenomenon of Samsung 4321 and Xerox 3119 should be relatively similar. Seriously. As for the HP 1136, if you print a large amount, it is best not to worry about it. The capacity of the toner box is low, and the toner detection depends on the chip. If you add toner, the waste toner will be full easily, and then black bars will be printed.

The Brother 7030 machine is more cost-effective precisely because the drum and powder are separated. Brother's drum core has a long life (printing 12,000 sheets or more), and it is easy to add powder. If you add powder once, you can print about 1,600-1,700 sheets. Now there are WIN7 drivers on the official website, so compatibility is not a problem. Also, the difference between the toner cartridge core that is usually replaced for you and the original drum core is the gear on one end of the drum core.
