I started noticing this today too.  My Macs aren't able to successfully
print, I just get an error in the error log about application/pdf being
an unsupported format.

If I take a PDF generated on the Mac and move it to my Linux system and
run "lpr <filename>.pdf" I get:
lpr: Unsupported format 'application/pdf'!

If I use "pdftops" to generate a PS file, "lpr <filename>.ps" works
fine.  If I open the PDF in xpdf and print, telling it to use the
command "lpr," that also works fine.

I upgraded from cups 1.3.10 to 1.3.11 today (cannot go back).  I've
rebuilt all the foomatic packages I had installed, gutenprint, cups-pdf,
ghostscript-gpl, but still it doesn't work...
