Ensure you are not printing a framed page. Browsers can only print individual HTML pages. Because framed pages contain multiple HTML pages, browsers cannot print them as they appear onscreen. You must print the contents of each frame as separate documents. No, Fusion doesn't require server side extensions.
Fusion disables components in previewed pages.
When you publish your web site, Fusion generates HTML code that references file assets using relative links, and places the file assets into the directory structure you specify. Fusion components should work as expected in published pages. If an error occurs when you publish your Fusion web site locally, ensure that you have enough hard drive space available. You'll also need to ensure that you can create files in the specified location. If an error occurs when you publish your Fusion web site remotely, ensure that you are connected to the Internet, and that your Base Directory setting is valid for your account on the web server.
