Pixma MG6320 2-sided printing no longer supported in Safari

[CC]

My Pixma MG6320 printer no longer supports duplex (2-sided printing) from my iMac desktop when printing from Safari. I had just upgraded the iOS from Maverick to Sierra, so I assumed Safari was also upgraded. I am now using Safari 10.1.1 with the Canon printer drivers 13.7.1.0. Interestingly enough my daughter's MacBook Air laptop running Apple's iOS El Capitan 10.11.4 with printer driver 1.0 works just fine.  When I am printing from Pages, this is not an issue.

Thanks.
