 =====Desktop Integration: Update system-config-printer for the New Architecture of printing=====
+contributor full-size (350 hours).
 Originally, we already had discontinued the development of system-config-printer and put it into maintenance mode, only fixing bugs and collecting UI translations.
@@ Line 170: / Line 172: @@
 But system-config-printer s still used a lot. There are practically only 3 printer setup tools around: The "Printers" module of GNOME Control Center, the printer manager of KDE Settings, and system-config-printer. There are many more desktop environments than just GNOME and KDE, and distributions using many of those use system-config-printer as their printer setup tool.
-For switching distributions into the New Architecture, meaning from CUPS 2.x to CUPS 3.x, the printer setup tool
+For switching distributions into the New Architecture, meaning from CUPS 2.x to CUPS 3.x, the printer setup tool needs to get appropriately adapted, to list IPP print destinations with appropriate configuration options, especially access to their web admin interfaces, and assign Printer Applications to non-driverless printers.
+One could also think about dropping the concept of printer setup tools altogether as modern, driverless printers are simply there, but it is not very intuitive for a user to have to find a Printer Application and install it to make a non-driverless printer working and that for driverless printers and Printer Applications there are web admin interfaces and how to access them.
+So to assure continued coverage of all desktops we need to revive development of system-config-printer and make it supporting the New Architecture, but as with GNOME Control Center and KDE Settings we also need to keep the old functionality, to allow a switchover to the new CUPS at any time and already while still using CUPS 2.x, have a better support for driverless printers.
+And this is the contributor's task in this project.

-=====Printer Application for Braille embossers=====
+=====Converting Braille embosser support into a Printer Application=====
+contributor full-size (350 hours).
+cups-filters currently supports Braille embossers through a series of PPD files and shell scripts that convert documents into a textual layout, convert the text into Braille dots, and convert the Braille dots to braille embosser-specific formats.
+For long-term support and wide availability, this needs to be converted to the newer CUPS infrastructure, Printer Applications.
+The contributor's task is thus:
+  * Converting these shell scripts into filter functions in libcupsfilters
+  * Creating a Printer Application that exposes Braille embossers configuration to users
+The contributor does not need to own any specific hardware, a comparison can be made between the output of the existing shell-script-based implementation and the output of the converted implementation.
