CUPS error under Fedora-8

[Timothy Murphy]

I get the following error in /var/log/cups/access_log
when trying to print on my desktop from a laptop
running Fedora-8:
---------------------------------
192.168.3.11 - - [12/Jan/2008:14:43:13 +0000] "POST /printers/lj HTTP/1.1"
200 159656 Print-Job client-error-document-format-not-supported
---------------------------------

Does anyone know what this means?
I'm trying to print the test page from localhost:631 .
There don't seem to be any other errors listed,
though error_log does have an entry
---------------------------------
I [12/Jan/2008:14:43:13 +0000] 
        Hint: Do you have the raw file printing rules enabled?
---------------------------------

Should I enable "raw file printing rules"?
Is this a change in Fedora-8?
What exactly does "raw file printing" mean?

I can print on the same printer from another laptop running Fedora-7.
I don't see any difference in the configuration of the two laptops
though I haven't checked this thoroughly.

As always, any advice or suggestions gratefully received.
