I don't understand.  Please explain.

This is correct.

This is correct also.

What is `text output'?

What is the `bad PS part'?  I have again difficulties to understand.
Please reformulate.

Option -Z just prevents the call of the postprocessor.  It does *not*
select the output device for which troff produces output.  If you want
intermediate output which is specially formatted for gxditview, you
must say

  groff -TX75 -Z

for example.  In `groff -V -Z' you only see the `-Tps' because it is
the default output device.
