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.

Graphics output isn't so hot; Can't scan in duplex for faxing

I have got this thing fixed for more than 5 times in last two months and still is not working fine.

The product it self is fine but after placing the order I could not track the item.

Have had this printer for 4 months and had 8 service calls on it already. Boards have been replaced and yet it cannot reliably work for a week without developing a new issue. HP has not been supportive when called or emailed, so we're eating the cost and getting something else.

Small footprint; HP PCL support

Unreliable; Have to change fax settings on device, not via UI setup; Non-descriptive error messages

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

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.
