Salut Pascal,

With darktable 1.7.0+97~ga09e199, I can modify all the parameters 
(including the  printer color profile) but I can't select the paper 
size. There is no preview and no print probably because of the lack of 
the paper size parameter. In a terminal : 
https://www.tuxdaddy.org/owncloud/public.php?service=files&t=d9b23c0417bc693dc5209ba9e2cda0b5

Selecting a preset cause a segfault. Backtrace available here : 
https://www.tuxdaddy.org/owncloud/public.php?service=files&t=4342bb107e29a14656ba2ae8b5696a2f

Joyeux Noel, Merry Christmas.

Jean-Marc
