The Brother HL-4070CDW is a wireless workgroup-orientated colour laser printer that can juggle simultaneous print jobs with ease. It prints at 2,400 dpi at a rate of 20 pages per minute, for both colour and monochrome, and Brother prices the machine below what you'd expect at that performance level. The HL-4070CDW also delivers duplex printing at a rate of 7 sides or 3.5 pages per minute. Standard, the HL-4070CDW has a 300 MHz processor and 64 MB of memory, and it achieves first print within 16 seconds if in its warm state. It achieves warm state within 37 seconds of power on with the default 64 MB RAM. It has a 250 sheet input capacity, and Brother rates the monthly duty cycle at 35,000 pages, but the recommended monthly print volume is only 500 to 3,000 pages.
The Brother HL-4070CDW is a light and dark grey machine with a squat cube design. This compact design gives it a small footprint, and the rounded corners and raised LCD panel provide it some style. The control panel only has a handful of buttons, and you access most features through the on-screen menu. The LCD screen is a tad small for these purposes. Another issue with the design is that the internal space is restricted, which makes it a little difficult to perform maintenance and change the Brother HL-4070CDW toner cartridges.
The Brother HL-4070CDW is a near perfect option for the small office that handles varied print jobs but only light printing duties overall. The HL-4070CDW is affordable, and its efficient long-term thanks to low-cost high-yield Brother HL-4070CDW cartridges. It has full support for both Windows, Macintosh and Linux operating systems, and since its wireless, it's very flexible in terms of fitting it into your pre-existing office environment. The HL-4070CDW delivers excellent performance in all that it does, and it's efficient in its use of power and toner.
The biggest issue with the Brother HL-4070CDW is that it's not a workhorse, and the warranty doesn't even fully cover it if you're printing more than 3,000 pages per month. Another issue is that the paper output system is not perfect, and at times, the system will output pages with curled corners. The Brother HL-4070CDW is also quite noisy to the point of screeching at times. The problem here is that this is a small office machine, and the noise may simply be too much for offices that are actually small.
