[cups] Missing letters into printed pdf docs

[Philippe Lefèvre]

Thank you very much for your replay Brian.

This issue comes only with certain PDFs, always the same. (Those which
are sent by my Bank).
I never noticed this trouble with other PDFs, reason why I first thought
it is an Evince issue.

The command line  lp -d <print_queue> <PDF> you suggest works well. All
letters are present.
So it seems to suggest that this it is not a CUPS trouble.

Do you think I should have a look with Evince/Cairo (I don't know well
these pieces of software but I'm going to crawl deeper in that way if
needed)
