I recommend "hp2xx" to read, display and convert to other formats,
your HP-GL files.  It does an excellent job, and I use it regularly.
It will convert to several other vector and some raster formats.  I use
it to convert to Postscript (actually EPS).

Go to "http://www.gnu.org/software/hp2xx/" to read about it, and
to obtain a copy.  If you are a Linux user, it may also be
available for your distribution (it certainly is for Debian).

Regards,

Dean
