I bought it for office use. The reaction time and printing time are very short. Another advantage is that I can connect to the router for wireless printing and mobile phone printing!Amazing!There is no need to buy a wireless connection. To be honest, it is very expensive.All laser printing consumables are expensive, so you should be clear that there is no choice. The price of a complete set of consumables is almost the same as that of a printer, which brand is the same.This machine is not separated from the toner cartridge. There is no separate imaging cartridge. If you don't mind the expensive consumables, this printer is a cost-effective laser machine at present.
