The Brother HL-4570CDW is the next model up from the. The primary differences are that this model offers faster print speeds and the added convenience of Wi-Fi support. However, it's a good deal more expensive as it costs around £520 online, which is around £200 more than its sibling.
In terms of design there's little to separate the HL-4570CDW from the HL-4150CDN, as they share the same chassis shape and colour scheme. However, as we quite like the cuboid design and mixture of the dark grey used on the main body of the machine and contrasting white side panels, this is no bad thing.
The control panel sits to the left of the paper out-tray at the top and has a pretty basic two-line display. There are also a limited number of buttons with just seven in total, including the Cancel and Go buttons. Nevertheless, the clean menu design means that it's still pretty quick to get at any settings you need to tweak.
We also like the fact that it has a secure printing mode. You can sending print jobs to it with a security code added, so the print will simply store the document in memory until someone presses the Secure button on the control panel and enters the correct code. It's handy if you're in a shared office and need to print sensitive documents like disciplinary letters or salary reports.
On the front you'll also find a USB port. This doesn't support PictBridge cameras, but has instead been added to allow you to do direct printing of PDF and graphics files from memory keys.
The main paper tray is housed at the bottom of the machine. It's a cassette-style, slot-in tray that can handle up to 250 sheets at a time. Above this there's a multi-purpose sheet feeder that can take a further 50 sheets and is mostly designed for printing envelopes and other odd-sized materials. There an optional 500 sheet feeder available as an add-on for those with particularly demanding printing needs.
This model uses four toner cartridges and these are all housed in a tray that's hidden behind a pull down panel at the front. The tray pulls straight out making changing toner cartridges a very quick and painless process. The printer comes with the toner cartridges pre-installed, but you do have to open up this compartment and remove some protective tabs before you can get going.
