this works with Acrobat Pro installed (with its default printer 
instance):

   open -b com.apple.Safari x.html
   osascript -e 'tell app "Safari" to print window 1 with 
properties {target printer:"Adobe PDF 8.0"}'

without Acrobat Pro, you could substitute a virtual PDF printer 
created using one of the approaches here:
