This option is greyed out in Monterey in Preview, currently a bug with annoying workarounds. Anyone running Ventura able to see if this option still doesn’t work?
you have an issue worth exploring; i've exported in preview to pdf a million times (ok, less) and works fine in ventura as well. can you export anything? a jpg, png? something's up....
EDIT: have you tried opening the print window then saving to pdf there? (instead of printing...)
Every so often it doesn’t let you do that. Yes you can export other files, it’s just that option. My wife was using it for work to make pdfs fillable instead of flat i believe. But in Monterey it’s just plain greyed out. Google search reveals it’s a bug for other users. So i was hoping it was fixed in Ventura.
