Mail stuck on "Generating content to print..."
I get this message in a popup whenever I try to print from Mail, whether it's the viewer window or the message window. There is a little progress bar but it never moves and the window just stays there so I have to cancel out of it. I've been have this intermittently over the last few months but now it's persistent. Rebooting doesn't seem to help. I have an HP Officejet 8600 that I've used for years. It prints with no issues from every other application so the printer is not the problem. I've searched here in the community forum but only see some messages that are about older OS versions. I'm on Sonoma 14.2.1 on a iMac with the M1 chip. Any suggestions?
