It means a print queue that goes through all the filters and final driver,
but then writes the raw information to a file instead of sending it to the
connection for the physical printer. CUPS-PDF is a kind of example but the
final driver is a PDF writer.

To set up a test printer:

1) Add support for file output in /etc/cups/cupsd.conf
FileDevice Yes

then restart:
/etc/init.d/cups restart

2) Set up printer queue
lpadmin -p foofile -v file:/tmp/fee

create location:
mkdir /tmp/fee

3) activate printer in interface:
http://localhost:631

4) You can see it here:
/etc/cups/printers.conf

where you can also change existing printers to use similar queues.
