Part of ValueFax software. Without "ValueFax Background" you will still be able to send a fax using the "Send Now" button of the ValueFax printer dialog. Of course, to send a fax, you will have to first select the ValueFax fax driver in the chooser since the ValueFax Background will no longer be running. You will also not be able to receive a fax, send a delayed fax or send a QuickFax.
