if you set LogLevel to debug in /etc/cups/cupsd.conf you'll see another
error message in /var/log/cups/error_log:

Print-Job client-error-document-format-not-supported: Unsupported format
'application/pdf'!

The problem is that firefox, beginning with version 5, seems to use pdf
instead of ps for printing. With Firefox 4.x and 3.x we don't have the
issue. 

The easiest fix is to modify cups' Pkgfile and change --with-pdftops=none 
to --with-pdftops=gs and rebuild the cups package. 
The drawback is that we introduce a circular dependency, because
ghostscript itself depends on cups. 

The second possibility is to install either xpdf or poppler and use 
--with-pdftops=pdftops with cups, which pulls in other dependencies.
Not very nice at all, but currently the only clean solution.

One idea might be to create a new port, maybe called pdf-utils, that 
includes only the cli part of either poppler or xpdf.


HTH and best regards
Juergen
