It's a different step. If you search around, you'll find "free" code and 
commercial code available for Smalltalk. I doubt there's any commercial 
offering for Squeak. There is SPL PDF Library at:
     http://map.squeak.org/package/d8fd5e1a-2bb7-4c99-a77e-f945dfce01eb

This code would load into your Smalltalk image, and generate the PDF 
file directly - you would have to make the appropriate API calls. You 
would not need to generate tex/latex format at all, in this case.

You'd want to generate tex/latex formatted output so you can make use of 
existing (non-Smalltalk) processors that would transform your tex/latex 
into a PDF.

Hope that helps.
