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=...

A couple of responses followed this posting. Here's my two bits:
Bill Thompson suggested using TVRD to read the image off the Wave-generated
X-Window, and then plotting the image to a Postscript file. Unfortunately,
this closes the X server connection, and any other Wave windows with it.
Rolf Diehl suggested using xwd, xpr and lp. This is a more general
approach, and has the advantage of being able to dump non-Wave windows as
well. Unfortunately, xpr is limited to at best a 4x4 dither representation
of color to a monochrome printer. It won't deal with color PS printers.
Also, I have been unable to render large windows, either by spreading them
across printed pages (-split n), or by scaling them (-scale n).
I've been looking at other alternatives, too. I've considered a variant of
Bill's method which would use DC_WRITE_TIFF instead of switching to
postscript. Then the tiff-printer (perhaps from Sam Loeffer's stuff?) could
be spawned. Again, this would require some contortions to print a non-Wave
window.
I guess the ideal solution would be to find a xwd-format to
PostScript-format converter. This would be similar to Rolf's solution, but
would avoid the weaknesses of xpr.
Does anyone know of such a utility?

I am not sure whether all implementations of X have xpr and xwd (utilities to
dump and print X-windows.) but if You have it You might try something like
the following procedure which I use to dump a window on my hp9k345 to my hp-paintjet.
If You change the options for xpr and lp that should work for any printer.
; TUB, Rolf Diehl; Tue Dec 17 21:20:39 MEZ 1991
pro xwd,nu
;dump window to the paintjet
;
;nu number or the WAVE window
;------------------------------------------
windowname=''
case n_params() of
0:begin
print,'Enter name of window to dump? '
read,windowname
end
1: windowname='WAVE '+strtrim(string(nu),2)
endcase
spawn,"xwd -name '"+windowname+"' | xpr -device pjet | lp -dpaint -oraw -onb "
end

The following will do the trick.
IMAGE = TVRD(0,0,!D.X_SIZE,!D.Y_SIZE) ;Read window as image
TVLCT,RED,GREEN,BLUE,/GET ;Get color table
SET_PLOT,'PS' ;Select PostScript
;
; Most color PostScript printers don't seem to able to plot all the way to the
; edge. Therefore, I make the area available for use by IDL somewhat smaller
; in the long dimension of the paper. The following shows the settings I use
; for landscape and portrait modes.
;
DEVICE, /LANDSCAPE, /COLOR, /INCHES, YOFFSET=9.75, XSIZE=8.5, BITS_PER_PIXEL=8
;
; or
;
;DEVICE, /PORTRAIT, /COLOR, /INCHES, XOFFSET=0.75, YOFFSET=1.25, $
; XSIZE=7.0, YSIZE=8.5, BITS_PER_PIXEL=8
;
TVLCT,RED,GREEN,BLUE ;Load color table
TV,IMAGE ;Display image of window
SET_PLOT,'X' ;Return to X-windows
You might want to play with the offset and size parameters to suit yourself.

Th pbm-package (portable-bitmap) includes a xbmtopbm converter, but I do not know
about a converter from pbm to postscript, but there are several other
converters for printers which might as well do the trick.
