"Capturing" images produces very poor quality.
there's xwd(1) and/or screendump(1), but here's another idea:

 library level changes (DISPLAYLIB) that record a history of
 what goes to the monitor (e.g., $LOCATION/.dhistory).  This
 would get wiped out everytime a frame is deleted or the screen
 is erased.  Then, write some sort of function that plays back
 this history, writing to a postscript file instead of making
 DISPLAYLIB calls.

Of course, rumor has it that someone is writing a postscript
paint driver.
