This seems to be because Graham has used an old version of dvips to
generate the PostScript file, a version of dvips that (incorrectly)
doesn't put any page information into the PostScript code.
I have a PostScript version (generated from the TeX source, via the
latest dvips) that contains page info. I also have a reduced-size
PostScript file (generated by running the previous file through mpage)
that will print two pages of text on each A4 sheet. They're quite big,
so I'm hesitatant to do this, but if there is public demand I could
upload them to if-archive.
