If you get a message telling you that no printers are installed, then it is most likely a permission issue. When you preview reports or save them as PDF the reports are run on the service tier. The service tier is configured to run in a specific user context. If this user does not have access to the printers on the system then you will get an error about missing printers.
Depending on your language this message could look like this:
- English: No printer installed.
- German: Kein Drucker installiert.
