    The files are in /tmp/medm.xwd*.  To have the file not deleted,
you need to modify the code.  The appropriate place is is printUtil.c
in the graphX/printUtils directory.  Do something near the bottom of
the file like:

#define DEBUG_PRINT
#if DEBUG_PRINT == 0
    strcpy(commandBuffer,"lp -d$PSPRINTER ");
    strcat(commandBuffer, psFileName);
    system(commandBuffer);
  /* Delete files */
    strcpy(commandBuffer,"rm ");
    strcat(commandBuffer,newFileName);
    system(commandBuffer);
    strcpy(commandBuffer,"rm ");
    strcat(commandBuffer,psFileName);
    system(commandBuffer);
#endif    

     MEDM requires the PSPRINTER environment variable to exist for
printing to work.  It should be set to a printer name for a printer
that accepts Postscript.

     There is also the Printer Setup... option under the File menu.
Invoking this will cause the environment variable to be set to the
printer of your choice (in the MEDM shell).

     I am not sure what you mean by "unhappy".  There will be some bug
fixes related to printing from 24-bit displays in the next release.
However, you still get somewhat reasonable output without them.
Otherwise, to my knowledge, printing works well.

     Good luck.
