I have plain TeX (NOT LaTeX) files that include EPS files using the psfig macros and dvips. These worked until today when I installed the latest TexLive distribution from the Ubuntu repository on Ubuntu 16.04. I now get the error: /undefined in startTexFig
appears to be the same sort of problem in the case of LaTeX, but the solution given is not applicable to TeX.
The Ghostscript version is 9.18.
The following stripped down example will trigger the error:
\input /home/poser/bin/tex/psfig
Some text.
\psfig{figure=Figures/ce1.eps,width=4.5cm}
more text
\bye
