You can disable two-sided printing on many Canon printers by using the printer’s control screen and/or by visiting the printer’s local admin web page, though you may have to dig deeply into the submenus.
I’m pretty sure that if you disable two-sided printing directly on the printer, it cannot be overridden by the driver on your computer, but I may be wrong about that.
