I have tried a number of mac based pdf creation printer drivers. The built in osx driver creates large files so I don't use it for drawings anymore.
I have caused the printer driver to create a postscript file and then used ps2pdf to convert that to a pdf. Much better filesizes, the quality of the output seems better but a pain to change page sizes and I have had it choke on complex drawings.
I now use Jaws. It has been flawless for me and well worth the cost. I should also say that I have not used the adobe distiller.
