As I understand it, it is not bug, but a feature.
That is the difference between *.eps and *.ps,
*.ps documents have pages, but *.eps should not have
pages, as I understand it, *.eps are for usage in documents,
they are not supposed to be stand alone printable documents.

Thomas,

I think I found the problem, and it must be in either octave or gnuplot.

There is a line in the CUPS error log for a non-printing file:

E [13/May/2008:15:03:13 -0700] [Job 818] No %%Pages: comment in header!

I looked at a file with no problems, and saw that directly below
%%EndProlog  is the line
%%Page: 1 1

I manually edited the non-printing file and added the line "%%Page: 1 1"
directly below the "%%EndProlog" statement. That file now prints.

So the problem is in the generation of the PostScript. This seems to be
a genuine bug, but is it an octave problem or a gnuplot problem?
