If you sel ect Remote Utilities Printer fr om the Printer List, the popup "Remote printing - preparing..." is shown, but when it closes nothing else occurs.
We can only fix the issue that we can reproduce during a test. Unfortunately, we weren't able to reproduce this one.
I've been trying Remote Utilities for more than a year, and it's a bit buggy. Remote printing, file transfer or lock screen not work good or not work at all definitely.
The only known issue with the File Transfer mode is that the remote directories are slow to open. This is a known bug (well, not actually a bug, it's the implementation) but we will fix it in one of the future updates where we will re-write this connection mode from the bottom up.
Regarding the lock screen, could you please elaborate on this problem and give us more information about what specifically is not working in your case.
