Something is blocking the print drivers from being registered on the computer or the printer does not support the page layout being sent to it (legal size pages).
Resolution: This issue can be resolved by ensuring the application is running as an Administrator.
Enable "Run as Administrator":
- Right click the WinMORE shortcut
- Select Properties
- Go to the Shortcut tab
- Click Advanced
- Check the run as Administrator checkbox
- Click OK/Apply
If this doesn't resolve the issue, try printing the report to another printer or even to a PDF writer. In some cases this message can be displayed when trying to print a report that prints landscape on legal paper and the printer does not support that paper size.
