In reviewing what your plugin instructions install, I noticed several
libraries were missing that had been installed when I had previously
installed the plugin using the hp-plugin script, and which are also
installed in my openSUSE Tumbleweed, namely
hpgt2500_ntdcmsdll-x86_64.so, libsane-hp2000S1-x86_64.so.1.0.25,
libsane-hpgt2500-x86_64.so.1.0.27 and libjpeg-x86_64.so.9.2.0.
Running hp-setup should download any needed binary blobs.
So I
added the first three to /usr/lib/sane and the libjpeg to /usr/lib, made
symlinks leaving out the architecture and version bits. Then I ran
`scanimage >image.pnm' again and it immediately segfaulted. By process
of elimination I determined that having
libsane-hpgt2500-x86_64.so.1.0.27 in /usr/lib/sane is what causes the
segfault, while with either or both of the other two libraries in
/usr/lib/sane, there is no segfault but hplip thinks no plugin is
installed. (The presence or absence of libjpeg.so.9 didn't make a
difference.)
What does ldd reveal?
That said, did you try the Arch PKGBUILD? They have a patch to remove
some of the closed source image processing stuff. It's been a bit, but
last time I tried it, seemed to work.

Arch is usually my first stop if I can't figure something out now days.
