Also reference previous quicky form I posted...

PostScript also supports high color depth and color management,
just not as easy...

PostScript also supports transparency, it just isn't as easy...

PDF is also used for international standards and printing/prepress;
we could just standardize on a particular version of PDF (e.g. PDF/is)
rather than chasing the latest version of PDF.

Other points:

     - PDF is already supported by CUPS
     - Current path for PS printers is: pdftops -> pstops -> printer
     - Future path for PDF-capable printers is: pdftopdf -> printer
     - Current path for raster printers is: pdftops -> pstops -> 
pstoraster -> printerdriver -> printer
     - Future path for raster printers is: pdftoraster -> printerdriver 
-> printer
     - Add discussion of job ticket stuff, and embedding them in PDF.

I can do a presentation on this...

It is worth noting that this can be done over time - the existing
driver will still work in the short term without changes...

     - Writing printer drivers - CUPS DDK, IJS, etc?
