batch PostScript

Dear Ferret users,

Some questions on creating PostScript output in batch mode.  I'm running
Ferret v5.40 under RH Linux v7.1.  Consider a simple shell script that
creates a map of the world:

cat << EOF | ferret -batch plot.ps >& /dev/null 
go magnify 
go basemap

1) This gives large margins around all the edges of the PostScript file,
even though I used "go magnify".  How can I eliminate or reduce these
margins? They don't appear when I produce a similar plot in the normal
(non-batch) Ferret environment.

2) If try another route and eliminate "plot.ps" from the script above, so
the output goes to metafile.plt, then Fprint doesn't work on that
metafile.  I get a series of error messages: "GKSM item 3 is undefined",
and the output PostScript file is blank.

Thanks for any help,
