[cups.general] Restrict print job based on MIME type

[Ari Constancio]

Hello again,

The printer in question (HP Laserjet 1300) is set with its PPD file;
with the script Jerome kindly sent, the MIME type appears as
"application/postscript" and not as "application/pdf" (I want to deal
specifically with PDFs).

I found no answers reading the CUPS manual or browsing the
mime.{types,convs} files.

Thanks again,
Ari Constancio
