html files are installed to the wrong path /usr/share/doc/hplip-3.9.2 /usr/share/doc/hplip-3.9.2/commandline.html /usr/share/doc/hplip-3.9.2/copying.html /usr/share/doc/hplip-3.9.2/devicemanager.html /usr/share/doc/hplip-3.9.2/faxtrouble.html /usr/share/doc/hplip-3.9.2/gettinghelp.html /usr/share/doc/hplip-3.9.2/hpscan.html ...
No longer relevant since 3.9.4b doesn't seem to install html files at all, and 3.9.8 installs it in the right location.
