If this printer is on a network there are reports of a spider or other pest (this is software not insects) that crawl the net for baidu.
The get you noted is pretty common and I'd like to hear more.
I am getting printouts daily on my Laserjet 451dn.
I have seen the older solutions for Windows OS but the Mac is different. There are no "installable options".
How do I stop these randoms pages from printing?
