Comment 2 for bug 1310157

  Hello again and thanks for your informative answer!

 The problem had already been filed upstream (bug 580055, https://bugzilla.gnome.org/show_bug.cgi?id=580055 ). It is caused by the program not handling correctly not having enough sudokus to print.

 An ugly work-around:
  1) Run dconf-editor.
  2) Search for gnome-sudoku
  3) Make sure that "generate-endlessly" flag, and the "generate-target-<difficulty>" flags corresponding to the level of the sudokus you want to print are set.
  4) Close dconf-editor
  5) Start gnome-sudoku. Leave it running a few minutes, to allow it to generate enough new puzzles.
  6) Print the sudokus.

 Best regards!
