Unfortunately there was a small bug in rpms - sorry for my mistake.
If you downloaded files before 21-08-2010, to fix it, create bash script which executes /opt/Printing/Printing and replace /usr/bin/Krokus with it.
New version - 0.6:
* rulers (which can be shown by choosing from Edits menu Show/Hide rulers)
* new dialog when closing - support for saving project
* some bugs resolved
