I am trying to configure a printer (Canon Pixma mg3150) to my mac... everything looks fine, I can print a page of 1 side. The specification of the printer shows auto duplex print, but the Two Sided is not permitted from the PDF viewer as follows:
Does anyone know if the printer really permits auto duplex print?
