I am trying to print black and white postscript in device resolution,
and have a few problems/questions:

1. my postscript image comes out with 00 and FB as gray levels, I
would like the latter to be FF so that output has white instead of a
pattern of dots for the very light gray FB represents. How can I do
this?  What is the array "convert" into which a linear combination of
"dacbox" entries are put, when colorps=no is specified, why 00 and
FF are not used as the only "colors"? (also see the (3) below). Why
"convert" is filled differently based on compression usage?

2. scaling of the image is defective: when I specify epsf=0
printer=psl/300 the page gets filled by a distorted picture. instead
of using the part of page for a picture of correct aspect. When i
tried epsf=1 and psl it could fit only a small part of the picture,
and ignored the landscape spec. The same scaling factor for both
coordinates should be used to keep the image proportions correct. To
cater for the need of forcing the use of the finest resolution the
device can provide a double scaling just before the "image" is a good
idea e.g. "72 300 scale 2048 1536 scale" for the case of a 300 dpi
printer printing a 2048x1536 image. Note that the first scaling is
from postscript default (always 72) to current resolution whether
fractint default or user specified. Forcing the device resolution
should be tied to a user specified option of course. Which one is
appropriate (or a new one?)  you guys think?

3. when epsf is not specified, even if the PS/PSL is selected as the
printer type,a *.prn file is generated, whereas epsf=0 with everything
else the same, a *.eps file  is output. Is this a bug or do I have a
misunderstanding of the options involved. I think a little more
explanation of epsf and its interaction with other postscript related
parameters would be helpful.

4. i think imagemask should be used instead of image when device
resolution is specified.

I can suggest fixes for last three as I have already corrected them on
*.eps files and tried successfully, but the first one seems little
more complex.  for which I need your advice.

Thanks in advance for responses...
