If you are the developer of the form, then you can just use a space instead of the "--select--" string if you want to control the displayed value. If you want to hide the "--select--" text when printing, you can add some custom JavaScript to the "Will print" action to hide the field and then add some JavaScript to the "Did print" action to display the field.
