Thank to Kurtis and Eric for that, which led me back to:

Something that was not clear was that imshow() exists after 
executing %pylab inline. Maybe the presenter's notebook did 
not begin with %pylab inline because he had invoked 
ipython notebook with --pylab inline option.

each notebook with a %pylab command.

I found PSDraw stuff of pillow that outputs postscript, 
then I used !ps2pdf to generate a PDF file. 
PSDraw is pretty crude, so I might modify it, 
or use something else such as ImageMagick or matplotlib's 
PDF capabilities as Eric wrote. Having the source code 
for PSDraw available at the click of a mouse while reading 
the dox, got me to look at it. There really is not much to it.
