I have tried unsuccessfully to include a LaTeX picture in a plain TeX file 
by using the following procedure:

1. latex myfile       %myfile.tex is a LaTeX source.
2. dvi2ps myfile.dvi > myfile.ps
3. create the file myfile2.tex

            \vskip 2 in    %space for the picture
            \special{psfile=myfile.ps}
            \bye

4. tex myfile2
5. lpr -d myfile2.dvi

I wasn't expecting any problems since this is not something funny like a 
macintosh picture.
Can anybody tell me what's wrong? Thanx.
