Funny, this doesn't happen in IDL, not even when called from inside a widget.

For the record, this is the method I use in IDL.

IMAGE = TVRD(0,0,!D.X_SIZE,!D.Y_SIZE) ;Read window into an array
TVLCT, RED, GREEN, BLUE, /GET ;Get current color tables
SET_PLOT, 'PS' ;Use PostScript device
TVLCT, RED, GREEN, BLUE ;Load color tables
TV, IMAGE ;Display image of window
SET_PLOT, 'X' ;Go back to X-windows

Note: Because most color printers seem to cut off the top and bottom portions
of the page, I usually use the following DEVICE statement for landscape
orientation.

DEVICE, /LANDSCAPE, /COLOR, /INCHES, YOFFSET=9.75, XSIZE=8.5, $
BITS_PER_PIXEL=8, FILENAME=...
