When it comes to laser printers, in most cases you can either get a lot of technology in a huge package, or just “a bit” of the same tech packed within a smaller case. But, that’s not the case with the Brother MFC-7860DW. As a $600 all in one device packed with features (Wireless connectivity, automatic duplex printing, a capacity of 250 sheers and a 10.000 pages duty cycle), this printer takes a surprisingly small amount of space, and besides the size, it’s also quite silent for a machine of this size. The unit can hold up to 12,000 pages and, since there is no color option, you only have to worry about the black ink. Once you’re finished with the first round of 12,000 pages, you will need to replace the drum unit, so let’s go and cover which exact model you need, how much it’s going to cost you and where do you actually buy a drum:
