When attempting to configure an older HP LaserJet 4000n printer using the Web Admin feature, several messages appear stating, "Your security settings have blocked an untrusted application..." and the Java application shows an error on the web page. Under normal circumstances Java is preventing an application that could be harmful to your computer. In this case we know this older Java application on the HP JetDirect card is likely safe and we want to allow it to run.
Follow these steps to add the website to the Exceptions Site List:
If you are concerned about security, you can remove these settings once you complete the printer configuration.
