Great product

The HP LaserJet Pro MFP M521dn ($899.99 direct) is a quietly impressive beast. Designed as a mono laser workhorse, with a 75,000 page per month maximum duty cycle and a 6,000 page per month recommended maximum, it can print and fax from, as well as scan to, a computer, including over a network, and it can work as a standalone copier, fax machine, and direct email sender. More important, it does well enough at everything it does to make it Editors' Choice for medium to heavy-duty use in a small to mid-size office or workgroup. There's nothing flashy here, like super-fast speed. In fact, it's easy to find printers, like the Editors' Choice Brother MFC-8950DW or the far less expensive Canon imageClass MF4770n that are faster. On the other hand, the M521dn offers a combination of features that make it more usable than most MFPs. MFP Features and BasicsIn addition to the basic MFP features I've already mentioned—printing, scanning, copying, faxing, and email—the M521dn can both scan ...

The HP LaserJet Pro MFP M521dn monochrome laser MFP is slower than expected for its rated speed, but it's strong on text quality and paper handling, particularly for scanning.

I work in an attorney's office - needed a replacement printer to keep the office running - ordered this one and it arrive at our office in LESS than 1 day!!. This printer/scanner is working like a charm so far. Thanks..

Printing is excellent in quality and speed. Scanning is fast too. Most of all, I like the feature of its wifi connectivity. I thought I couldn't print or scan wirelessly with this printer unless I buy a wireless printer server. I was wrong, fortunately.

We got this AIO laser printer during the X'mas season; very good deal to replace our MFP1536, but much faster than 1536, overall we are happy with this machine;

Two side printing; Two side scan; Plug and Play (almost; Easy to use; Fast respond

Kind of Expensive

Ordered for a smaller office (15 people). Has been a great printer, scanner, copier and fax machine. Next to faxing, scanning to networked PC's is the most common use. The duplex scanning for two sided originals is especially handy. Very good quality printing.

We've been using this printer for a couple of weeks now. Setup is straight-forward, and the printer/copier/scanner is fast and reliable. Very impressed with this model and its embedded HP print engine. I highly recommend this for a small office as a shared network printer/scanner/copier.

Brilliant printer for the office. The HP LaserJet Pro M521dw combines fax, scanner, copier and printer into one small machine which will sit neatly on a desk or bench. I find it very convenient that it works both wired and wireless.

I own this printer but the sleep function causes probles all the time , you have to reboot the printer in order to wake up and that is some thing you have to do several times every day
