Remote Utilities only transfers the print file from the remote PC to the local PC in a special printer interchange format, understood by all printers. When printing the file to your physical printer on the Viewer side did you play with printer options in the standard Windows Print dialog?
Both these options can only be possible with RU Server rather than with our default (corporate) server, for obvious reasons. We'll take a look at your suggestions and see if we can implement them in subsequent releases.
The possible explanation is that when you restart using Power Control mode in RU, forced restart is used. That is, even if there's an unsaved work/document or unfinished process on the remote PC, the system will restart anyway.
