I am trying to print to the Disk Tray.
I put the tray in but the printer does not recognize it. I try to select the tray as an option in my print settings but there is no tray option there to select (Photoshop, MS Word, PDF, etc).
When I look to the manual for how to print to the tray, it only gives instructions on how to print using Canon's consumer-grade printing app.
Please help.
I am on a Mac Pro running Yosemite.
The printer is plugged in via USB.
