    Fix Wine Internet Explorer Print hang (#5064)
    
    
    When using wine internet explorer it crashes if you click print even if you click
cancel, this fixes that issue.
    nsIWebBrowserPrint_Print apparently causes issues for unknown reasons.
    
    JIRA issue: CORE-16884
    
    By returning S_OK print doesn't cause a crash.
    Use ERR and S_OK return before hitting nsIWebBrowserPrint_Print
