[Image-SIG] PSDraw in PIL problem with print

I am trying to follow the Postscript print example in
PIL. So I am using PSDraw to create a new ps file from
a jpeg. I have ghostview installed, so I can view the
resulting ps file (when it is produced successfully).

Example from PIL Manual:

import Image, PSDraw
im = Image.open('lena.jpg').convert('L')
box = (1*72, 2*72, 7*72, 10*72)
outfp = open('lena.ps','w')
ps = PSDraw.PSDraw(outfp)

Now when I try to open up the lena.ps (that should
contain the lena.jpg) in ghostview, I get Error:
undefined gsize. However when I change the gsize to
gsave in the lena.ps, the file loads up. Snippet of
the actual code is show below:

gsize ------------------> change this to gsave
240.000000 384.000000 translate
0.960000 0.960000 scale

I don't know why it is happening. Can you please tell
me another solution instead of changing a line

I just need to print a jpeg file. Is there any way
else to do this. So basically I have an image in a
folder, I open it and send it to a printer. 

Please let me know if you guys know anything.
