It's a Pro-1000 printer. Not sure how that would affect a Canon plugin vanishing from Photoshop every few days, but there you go. Also, there is nothing in the Canon database about this. Also calling support at Adobe and Canon about this today. Not looking forward to the loss of time for what will probably turn out to be a fool's errand. What I think is happening is the M1 chip is not compatible with the Intel version of Print and Layout. The plugin needs updating to make it stable. That's my guess. I couldn't be running a more up to date system. I can print, it's just annoying to have to close Photoshop and Lightroom every two days or so and reinstall the plugin. Started with the Mac Studio, which I updated to about three weeks ago. Canon plugin is not optimized for M1 is all.
