[Samba] Samba + cups not working (intermittently)

[Robert S]

I initially thought this was a cups problem, but looks like samba now . . .

I have been using a Brother MFC9880 printer with Samba.  Everything has been
fine for the last month, until things stopped working recently (on a Monday
morning with no intervention over the weekend.  Samba log is below:

My system:
Debian woody
Samba-2.2.3a-14.1
cupsys-1.1.14-5woody1

MFC9880 connected to server by USB.

This has intermittently happened in the past and can sometimes be fixed by
restarting samba/cups, but I can't affort outages in a busy office!!

BTW - printing using cups by http (http://debian:631/printers/mfc9880) from
windows client works fine - so I think the problem is with samba.

Can anybody help??
