Lost ability to do double-sided printing to Canon MX-860
Hi folks,
I'm running MacOS Mojave, 10.14.6 with a version 16.10.0.0 printer driver for the Canon MX-860. In a recent move, the network addresses changed and I reinstalled my printer to get it working. The new printer dialog does NOT have the "Duplex Printing and Margin" item that used to be there. I do have "Layout" as an option there, with a "Two-sided" item which is greyed out. This all means that I can no longer print double-sided, which is a real loss. I downloaded the most recent "Canon IJ Network Tool Ver.4.7.2" from Canon and installed another instance of the printer, but I see the same thing. Can anyone give me an idea of how to get this working again or explain why it can't?
Thanks,
