I have a WC 3345, and I obtain a strange behaviour whenever I set the print quality to "advanced" in the windows drivers.
Moreover, the manual does not seem to clearly explain where to adjust the parameters corresponding to the "advanced" print quality entry.
The actual problem is that whenever the print quality is set to "advanced" (see image below), in every duplex print the second page is shifted to the side of the sheet. I created a sample 2-page pdf and I acquired the back one, the original second page and the acquired counterpart follow below. (I put the images one below the other to highlight the shift to the right.)
Why this happens and how can it be fixed.
