Pros and Cons of PDF print queues?

Also, the fact that its not a general programming language, so you can't write a raytracer in a PDF is kinda nice on the server side.
Also, I think there is some metadata storage in PDF so that you can tell the printer things about how to print the document, etc.

- PDF can handle CJK and other large font sets without the hackish and painful workarounds required in PostSCript, which was designed assuming that an 8 bit character index was all you needed.
- PDF can handle alpha channel color. The PostScript work-around for the lack of alpha-channel support is to expand all the relevant areas into bitmaps with pre-merged colors rather than carrying forward overlapping vector-based elements with transparency. This works so poorly that I hesitate to even call it a work-around.
