This is an old problem / FAQ. Since I don’t always print web pages, this is a new discovery.
When trying to print a page with flash content, the flash content is blank. This uses the browser’s build in print function called from File > Print…
To print the flash content, right click anywhere in the flash content and select ‘print…’ from pop up menu.
The pop up menu when righ-clicked from flash content looks different from ‘standard’ popup menu when you right click anywhere on a non-flash content.
I don’t use IE so i don’t know if IE has the same problem. If you use IE, it’s appreciated if you could leave a comment and let me know the behavior.
