I know this is an older topic, but it comes up first in a web search .  We are having this issue with an M452nw randomly.  All settings are fine- 1 copy in web interface and mopier mode disabled.  

 

What I found to be the problem is Windows moving the printer from a specified IP Port to a WSD Port.  When it's on the IP Port everything works fine, but as soon as Windows 'decides' that a WSD Port would serve the system better, then problems occur- print jobs do not get deleted from the spooler, multiple copies print, etc.

 

Manually move the printer back to the proper IP Port and then disable WSD as explained Here

 

Hope this helps other IT Admins!

I was stumped why my MP LaserJet MFP M476dw was multiplying the number of copies times itself (and I guess I still am) only when I printed from Word (I didn't do much testing with other programs) only when I printed while connecting through COM with a AHK script. I enabled "Mopier Mode" and it fixed it instantly. I am confused why, but at least it works! Hopefully having it enabled doesn't cause further problems.
