Change it from 2 Sided to 1 Sided and then scroll down the page until you see the Set Default Options button.Ĭlick on this button to save the change.

To enable it, open Terminal and type 'sudo cupsctl WebInterface=yes' (without the quotation marks). By default on 10.8, access to the CUPS page is blocked. You can change the default via CUPS, which is the core printing system of OS X. I just found it about 10 minute ago and it WORKED! I did a little happy dance I was so excited! This will change your default PERMANENTLY so you SHOULD never have to worry about double-sided ever happening by accident with any program. I have something you guys should try that are using Macs. And the weird part was always through the Adobe Pro.
For the last two days I have tried my friggin hardest to figure out why the heck this Mac kept printing double-sided to the Brother pinter I use at work. I think I have the angels singing finally on my end.
