Pros: It looks pretty nice for the price. It printed really fast when it did print, and the quality was acceptable most of the time. The toner was cheap.

Cons: The scanner was a terror. It took approximately forever to scan anything through the Automatic Document Feeder and it would fail roughly half of the time. Of course, the scanning software would destroy your work and force you to start over. It once took me close to 45 minutes to scan 10 or 15 sheets this way. Completely unacceptable. The Ethernet port or NIC on the printer was extremely flakey since day one. I don't know if I got a bad model nor did I want to deal with HP's amazingly awful support to explore options, but it would be reachable and remain on the network until the moment you sent it a print job of any size. It would complete the job or even let you run another one if it was feeling generous and then become randomly unreachable until it was hard-rebooted. This made remote scanning LOTS of fun. The fax machine never worked for me. I have one line in my apartment and wanted the printer's fax machine to share it with my phone and voicemail. Most printers let you do this. This is not an uncommon scenario. It was impossible to set this up with any permutation of the settings available to me. For what its worth, I was able to set up faxing on my new Brother 7360N in all of ten minutes, testing included. To top all of this off, it randomly decided to put itself in a hard reboot loop. All it would display on the screen was "No strings in RO;" this apparently meant it was due in for a firmware upgrade, but the unit kept resetting itself during the flashing procedure, so I don't think that was the cause of this.

Overall Review: Surprisingly, I bought several M1536DNF's for the company I work for and they all work amazingly. I don't understand what happened here, but the poor design and quality of this unit made it pure hell to use from the moment I bought it to the moment I chucked it. Having said all of this, this printer would be *somewhat* acceptable if it were the only laser printer at this price point, but it's not. Not even close.
