samba - Apr 2004 - lots of (invalid???) printer errors in the messages file

Hi,

I have a samba 3 server running on Linux that appears to work quite 
hapily apart from it generating loads of error messages in the messages 
file.

This is what I get in my messages file:

Can anyone advise me how to stop these occurring.

Thanks in advance
