IPP scan (or virtual MF device) server (Scanner Application)

Introduction

The Internet Printing Protocol (IPP) does not only support printing, but also scanning, as there are many printers which also have a scanner (multi-function (MF) devices). Both CUPS and the developer tool ippserver emulate IPP network printers but not IPP scanners and so they cannot serve as a server to share a local scanner.

This task is about adding the scan server functionality. If you have a scanner connected locally (and it scans via SANE), share it as an IPP scanner, advertising itself and accepting jobs using the IPP driverless scanning standard. In contrary to SANE-based network scanning clients with any operating system, also phones or IoT devices can scan on your shared scanner.

Also old hardware can be recycled to a modern MF device.

This server software will be a so-called Scanner Application, a sample implementation of the future form of scanner drivers, easily packageable in sandboxed, distribution-independent package formats like Snap.
