I think PDF is no good; I think is too messy. I think that better formats can be possible, such as maybe PCL, and I have some of my own ideas of making a better format, too. However, PDF is a commonly used format. When I wanted to generate PDF (or other formats such as PNG), I just wrote a PostScript program to do (and then run it through Ghostscript). (Drivers could also be added to make other output formats too if wanted.)
