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.
