Preview App And PostScript Conversion [was color laser printers]

[steve harley]

Preview (or rather the OS support in general) isn't really that 
great at PDF either; i very often encounter PDFs that the OS 
cannot display properly; not all of these are generated by Adobe 
apps; this one has bedeviled me lately:

<http://denvergov.org/Portals/193/documents/station%20area%20profiles/Alameda.pdf>

even though it's PDF 1.3 (which supposedly Mac OS X fully 
supports), much of the content is blank in Preview, but fine in 
Reader or Acrobat Pro; i'd really rather use Preview for ready 
reference because it is a much lighter weight tool
