[Samba] 4.1.5, spoolss_connect_to_client and negotiated protocol

Hi @all,

experimenting with 4.1.5 and printing I have messages like this in the log:

spoolss_connect_to_client: machine X didn't negotiate NT protocol.

machine X is a windows 7 machine.

I have following definitions in smb.conf:
  lanman auth = yes
  client lanman auth = yes
  client plaintext auth = yes
  client ntlmv2 auth = no
  max protocol = SMB3		# <---------------
  min receivefile size = 16384
  aio read size = 16384
  aio write size = 16384
  client max protocol = SMB3	# <---------------
  acl allow execute always = yes

Is it possible that a higher protocol will be negotiated with modern 
clients with these options?

Can I quiet these messages with

  print notify backchannel = no

(no connection attemps from server to client)?
Shouldn't the "print notify backchannel" default be "no" in 4.1.5 regarding
