How to add total page count in PDF using reportlab

Question

   def analysis_report(request):

       response = HttpResponse(mimetype='application/pdf')
       response['Content-Disposition'] = 'attachment;filename=ANALYSIS_REPORT.pdf'
       buffer = StringIO()
       doc = SimpleDocTemplate(buffer)
       doc.sample_no = 12345
       document = []
       doc.build(document, onLaterPages=header_footer)

   def header_footer(canvas, doc):
       canvas.saveState()

       canvas.setFont("Times-Bold", 11)
       canvas.setFillColor(gray)
       canvas.setStrokeColor('#5B80B2')
       canvas.drawCentredString(310, 800, 'HEADER ONE GOES HERE')
       canvas.drawString(440, 780, 'Sample No: %s' %doc.sample_no)

       canvas.setFont('Times-Roman', 5)
       canvas.drawString(565, 4, "Page %d" % doc.page)

I above code i can bale to display the page number, but my question is how can i display "Page X of Y" where Y is page count and X is current page.

I followed this http://code.activestate.com/recipes/546511-page-x-of-y-with-reportlab/, but they explained using canvasmaker, where as i'm using OnlaterPages argument in build.

How can i achieve the above thing using canvasmaker or is there any solution using OnLaterPages ?

Here is the improved recipe http://code.activestate.com/recipes/576832/ which should work with images.
