Project Ideas
Wrapping proprietary printer drivers into a Printer Application
Introduction
With sandboxed packaging, Linux distributions appear which do not use classic RPM or DEB packages any more, like the all-Snap Ubuntu Core. As a result CUPS will not work with classic PPD/filter-based printer drivers any more but requires all drivers being provided as Printer Applications. The student's task is to add this functionality to the Printer Application framework and create an easy way for users to install proprietary printer drivers into that chroot-equipped Printer Application.

Support for IPP Fax Out
Introduction
IPP Fax out is a feature which is currently missing in Linux unlike Print and Scan. The student's task here is to make this functionality easily accessible for users of common desktop Linux distributions. Like printers, faxes should automatically appear on the system and get available in print dialogs and if one prints to a fax, fax-specific options should also appear in the print dialog and the user should be able to pick phone numbers also from contacts.

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.
