The Brother HL-4050 is a color laser printer designed for the small to medium office environment. With built-in networking and a convenient USB port, it has a lot to offer. Duplexing capability is available in some models. These features, among others, sets this unit above the competition. Paper capacity is 250 sheets for its main tray and 50 sheets for its multipurpose tray. An additional 250-sheet tray can be added later for expansion. Standard Brother HL-4050 toner cartridges have a capacity of 2,500 pages for black and 1,500 pages for each color cartridge, but high-yield Brother HL-4050 toner cartridges are available with capacities of 5,000 pages for black and 4,000 pages for each color. Print speeds are fast, around 20 pages per minute in both color and monochrome.
