Can the PDF pseudo-printer in CUPS be configured to emit PDF/A files? If so, how to do it?
I'm using CUPS 1.5.3-5 and CUPS-PDF 2.6.1-6 as provided by Debian Wheezy/7.0.
Despite CUPS PDF Format - Documentation claiming that "CUPS PDF files (application/vnd.cups-pdf) are device-dependent PDF/A files that contain a job ticket information.", at least one online validator claims that a to-PDF print of itself from the web browser "does not conform to PDF/A".
