Solution 1:

You can add style="display: none;" on you buttons and then do this in your tinymce configuration:

tinymce.init({
    ...
    setup: function(editor) {
        editor.on('init', function(e) {
            $("#doc_send_email").css("display", "block");
            $("#pritn_pdf_btn").css("display", "block");
        });
    }
});
