Before contacting Kamp-Data's technical support, please search the Known Issues for documentation on your error. If your error is not documented on this website, then please try printing the report with and without SQL Optimized enabled. Quite often, the non-SQL Optimized reports can still successfully print when the SQL Optimized Reports fail with an error.
The next step should be to notify Kamp-Data's Technical Support of your error via e-mail. See Contact Us for more information. Please send a brief description of your situation, the results you have found so far and if you can, please provide screen prints of your error message(s) and the DZ Report Options window.
