Summary: First, let me address the printer itself, which deserves five stars for its operation under Windows 8.1. Read and follow the instructions that come with it, and you'll find installation is very easy. I installed to my home LAN via Ethernet (using a Windows 8.1 Pro computer), and I was printing within just a few minutes.
Summary: I ordered this, as I needed a new printer. As I'm a (perpetual) college student, I use laser printers for their large print capacity and relatively low print cost. I previously used a budget laser printer (HP in the ~$100 range) that served me well, but had driver issues with my mac and couldn't do network printing. After much debate about what features I wanted vs. needed, I settled on this unit.
Summary: The 5450dn does everything well. Every device inside LAN prints after a quick setup, including wireless devices. Print quality is stunning and your hard copy is there when you hit print. A bonus over prior Brother laser I had is the status monitor that runs in system task bar shows real time feedback (such as out of paper) that beats idiot lights which idiots never seem to notice. The only minus I have for this printer is the fragility of the physical construction.
Summary: I have had this printer for about eight months now. It prints quickly and I really like the duplex. The airPrint sometimes doesn't work if the primer is asleep. I need to wake it up to make it work, but it prints from my iPhone and iPad. Haven't had to replace the toner yet.
Reasonably priced Brother printer with decent performance

Summary: We have used Brother monochrome laser printers for over 15 years. They have always been reliable and have a reasonably good performance. We usually replace them when the drum needs replacing as the cost for drum replacement is nearly the same as buying a new printer. This one is reasonably fast, has built in duplex printing, supports AirPrint and has a built in network connection. It does not have a wi fi connection which was not a requirement for us.
Summary: I had gotten completely fed up with inkjet printers. (What? I'm out of Cyan ink so I'm not allowed to print in black only?) I don't do a lot of printing, but every time I needed to print something, there would be something wrong with the ink-jet. It had either run itself out of ink by constantly cleaning the print heads or had phantom "paper jams" where no paper was actually jammed anywhere.
Summary: I have little to add to the many reviews here already except to say a bit about the history of the printer, and how it compares to previous models and HP. I also ran some simple tests on print quality. Many of us who do some desktop publishing, or just some serious printing from time to time, appreciate a good laser printer.
Summary: I bought this even after reading negative reviews that it draws too much power. That part is partly true - It turns out that my flouroscent desk lamp goes off while printing, but the circuit breakers are fine. One of the purchase criteria was a low cost of consumables, and I am glad this supports a high capacity 8,000 copy cartridge for only $79. Installation was a breeze on Win XP and Win 8 computers with the included CD.
