There are thousands of file extensions out there. Your desktop manager may not have a predefined behavior for what to do with the specific file you're trying to open. A driver for a printer in your case, I would just download somewhere locally and point to it when you add a new printer. I would recommend against using automatic file execution or opening from removable media. That can be dangerous, especially if you're running with elevated privileges, and not to mention very Windoze-like. Unfortunately it is the default behavior with some window managers.

When I have a file or a program on a dvd I just insert it into the drive and it will usually install itself. When I download a file or driver such as a driver for a printer it get's on my desktop with the questions open/install with! I really have no clue how to open and install with what. -- ubuntu-users mailing list <a href="mailto:ubuntu-users@lists.ubuntu.com">ubuntu-users@lists.ubuntu.com</a> Modify settings or unsubscribe at: <a href="https://lists.ubuntu.com/mailman/listinfo/ubuntu-users" target="_blank">https://lists.ubuntu.com/mailman/listinfo/ubuntu-users</a> </blockquote></div>
