When trying to print in anyway in Outlook you are presented with a popup with the error "Cannot print unless an item is selected. Select an item, and try to print again."
This can be easily fixed!
- On the machine in question go to %appdata%\Microsoft\Outlook
- Find the file OutlPrnt and rename it to OutlPrnt.old or delete it. Doesn't matter much.
- Restart Outlook and try printing again
Most probally cause of for this issue might that the file became corrupted. renaming it simply forces Outlook to generate a new one.
