Can I print out a hard copy of a vault?

Keep in mind @PatMax that you are exporting in an unencrypted format in order to print. So that local file would be susecpitble to both any malware on the system, and the printer (which sometimes retains cached copies of printed docuements, or can also be infected with malware, as users rarely update printer firmware or drivers when necessary - and printer companies are notoriously bad at ensuring that these are up to date).

That said, you can use the csv generater in the https://1password.community/discussion/101693/moving-to-1password-from-another-password-manager to convert to CSV, and save/print that. See the README. Please take care when doing this.
