Here is exactly what I am using which works great, hope it helps ;-)

    self._doc.build(
            self._story,
            onFirstPage = self._on_page_one,
            onLaterPages = self._on_pages,
        )

    def _on_page_one(self, canvas, doc):
        canvas.setAuthor("Academic Records/Accessible")
        canvas.setTitle("PolyProgress Degree Audit")
        canvas.setSubject("Degree Audit")
        self._on_pages(canvas, doc)

    def _on_pages(self, canvas, doc):
        audit_ver_info = "%s, data refreshed %s %s" % (
            self._audit_version,
            self._refresh_date,
            self._refresh_time,
        )
        canvas.saveState()
        canvas.setFont('Helvetica', 8)
        canvas.drawString(0.5 * inch, 10.5 * inch, audit_ver_info)
        canvas.drawString(7.5 * inch, 10.5 * inch, "Page %d" % doc.page)
        canvas.restoreState()
