I have been able to print onto printable CDs and DVDs in the past with the MX922 without issue. Now when I try to print, from Image Garden, everything is fine until I hit print, then the printer tries to print on paper from the upper cassette rather than telling me to open the slot to install the sled that holds the disc to be printed on. I've checked every setting, the only thing that has changed is the operating system on the computer. I'm now running Mac 12.6.1. I have deleted and reinstalled all the Canon software including the latest version of Image Garden and the printer driver.
