The error from __gnplot_print__() is something different. That function only is
called by print().
Running 3.4.0, I checked ...
x = 0:10;
plotyy (x, sqrt(x), x, x.^2);
h = legend ("root", "squared");
set (h, "fontname", "Courier")
print test.eps
print test.png
... I encountered no errors, and obtained the expected results.
Can you provide a simple example that produces the __gnuplot_print__ error ?
