You would only have /etc/cups/ppd/PDF.ppd if you had cups-pdf installed.

Viewed with mupdf, xpdf and evince it's almost acceptable if you squint
at it. Viewed with Iceweasel it is awful. The PDF has been created by
cairo 1.9.5 so I guess you have printed to file from a GTK application
like Iceweasel. CUPS is not involved in this process.
I am away from my equipment at present so have not printed the PDF, but
would expect CUPS to print what it is given.
pdffonts shows
[none] Type 3 Custom yes no yes 6 0
[none] Type 3 Custom yes no yes 7 0
GIDVTL+TeXGyreHeros-Regular CID Type 0C Identity-H yes yes yes 8 0
[none] Type 3 Custom yes no yes 9 0
[none] Type 3 Custom yes no yes 10 0
CCYKOU+DejaVuSerif CID TrueType Identity-H yes yes yes 11 0
Perhaps using a different font setup with the application would help.
