This is exactly what I don't like in Thanh's thesis (to be found at 
http://www.pragma-ade.com): That you have to creep pagewise through a 
document of more than 100 pages, though we're living in the hypertext age.

The initial question seems to be answered at the very end of Thanh's 
samplepdf.tex file (to be found at 
http://www.ctan.org/tex-archive/systems/pdftex). Using a pdfTeX 
primitive, we can get a lot of free screen space by simply saying:

\pdfcatalog {%
  /ViewerPreferences   <<
    /HideToolbar  true
    /HideMenubar  true 
    /HideWindowUI true >> }

But now that we're discussing ways to annoy the reader I would like to 
know whether there is method to protect a portable document file (a 
little bit, at least) from being printed by the users.

I've heard that Stephen King used that feature when publishing one of 
his popular novels at the internet (and of course it was hacked within a 
short time).
