Recommendations for a flatbed scanner for artwork compatible with iPad Pro

Brother multi-function printers (and presumably Brother scanners, but I’ve not used a dedicated Brother scanner) can print and scan using an available (free) printing and scanning app from Brother, and can also print using AirPrint.

The app:

Which Printer Should I Buy? - Apple Community

I’m using some older Brother multi-function printers, and they scan just fine.

HP, Epson and Brother are all popular and capable choices for Scanners, Printers and multi-function devices that incorporate both. Which make and model that you ultimately choose will be determined by your personal preference and the technical specifications that most closely align with your needs.

Scanners and multi-function devices that are suitable for use with iPad will clearly state compatibility with iPad/iPadOS in their specifications.

All scanners used with iPad will require use of the respective manufacturer-provided (or third-party) App for scanner functions. While AirPrint is a driverless protocol for printing documents from Apple devices to compatible printers, scanning is not supported by AirPrint. The manufacturer-provided companion App includes the necessary driver software for scan functions.
