SMB packet and secure channel signing

I have a client who recently bought a Canon printer / scanner (one of the
big network models).
The canon people are telling me that in order for the scanner portion to
work, SMB packet and secure channel signing must be turned off......
(this is set in Group policy-Domain controller -- administrator tools /
domain controller security policy / MS network server / Digitally sign
communications - they want this policy turned OFF)

If anyone has any knowledge on this,
My question is what ramifications this will have to the network as a whole.
All XP Pro clients
Remote access via RWW IS used...

This KB article
http://support.microsoft.com/default.aspx?scid=kb;en-us;823659 explains what
this is and some ramifications (look under Security, #4)

((this also seems to be a way to fix the problem with Pre XP clients logging
onto a W2K3 domain..
But all I can find about it is basically "Microsoft does not recommend this
setting" (to turn it off)
http://support.microsoft.com/default.aspx?scid=kb;en-us;811497


Any of you very knowledgable peoples has an opinoin about this?
Not really a big deal?
DON'T DO IT?
What sort of ramifications could I expect if we turned it off?

If I turn this off, will remote users doing remote control over RWW and
using for instance a W98 remote system have any issues (I would think
not...)

Thanks
