I'm using the IFrame module to display some content from another one of our internal servers on our internal website build in DNN. When a user tries to print the page through the browser, instead of printing the content in the IFrame, the print-out prints a 404 error. However, if the page is viewed in a Print Preview mode, the content within the iframe is displayed. Printing from Print Preview prints the content as it should.
Why would this be happening and how do I fix it?
