/**
 * PrintModal with several sliced files marked in the File Manager (#3462).

 * The selection used to always become printer alternatives (#671): one job, the
 * first free printer of a matching model prints its file. Two files for the same
 * model could therefore not be queued at all ("variants must target different
 * printers"). The dialog now asks what the selection is: alternatives, or one
 * queue item per file in list order, with the ordinary printer picker and
