John,

As you guessed, the XWP driver is the GUI combination of
both the PS and XW device. This lets you print PS files
from the GUI.

For creating a postscript file from GDCROSS (and other text interface programs),
use the DEVICE=ps|filename|x;y|type
where x;y is 8.5;11 for portait and 11;8.5 for landscape
(or 11;17 / 17;11 if you have a printer that has that size paper tray).

The "type" is either C for color postscript, G for grayscale, or
M for monochrome. After running the program, be sure to run gpend for the
postscript file to be finished/flushed. 

The above may duplicate what you already know if you've been sucessful
in using the PS driver and were only referring to XWP.

The other generally useful drivers are "gif" for gif images
without having to use an X server, nc for meta files for NTRANS,
tiff (like fax maps used), or vg (vector graphics). 

The nice thing about the VG driver is that you can then display the
products in gpmap using the VGFILE parameter, or imported into
NMAP2 for use with the drawing tools to annotate, or display with
other daya sets.
