Does anyone know how to set the default banner page for CUPS ?

According to the docs, a client can specify it like:

lpr -o job-sheets=standard filename

where standard is the name of the banner file.

But I'd like to set the default banner for all print queues on the server
and then not allow the end-user to override.  I do not see anything in the 
cupsd.conf about banners or job-sheets.  I see job-sheets in printers.conf 
but that appears to be a generated file and my attempts to modify it do 
not seem to effect any change.

I don't see anything the CUPS Software Administrators Manual about banners.
And the FAQ simply says:

The "job-sheets" option in CUPS 1.1 allows you to specify a banner page for printing. Look in the /usr/share/cups/banners directory for the available banner files.

Any help is appreciated.  Thank you.
