serwap [1] filed a merge request for canon-cque [2]:

The canon-cque contains also some executables (e.g. CQue.exe, which executes, despite the name, on linux too). CQue is needed to configure the printer's credentials, like department id and password - you cannot do it with generic cups interface. Can CQue executable be installed as well?
