what about scanning to WebDAV/Nextcloud/SMB-Share/Paperless-NGX?
Manufacturers seem to have by and large decided that those features are reserved for professional office units priced at >$400, and for everything that can't scan directly to network drive without a computer you can only operate the machine directly (ie pushing the buttons on the machine) if you have Windows or Mac. Linux users must use a desktop app, browser interface, or smartphone app.
