So we have setup a test machine (a clone of the original machine) and 
upgraded to 4.16.4.

Here 4.16:

cn at printsrv-test ~]$ rpcclient printsrv-test -U cn -c "enumprinters"
Password for [DOM-02\cn]:
No printers returned.

[cn at printsrv-test ~]$ smbclient -L printsrv-test
Password for [DOM-02\cn]:

	Sharename       Type      Comment
	---------       ----      -------
	print$          Disk
	IPC$            IPC       IPC Service (Printsrv-Test)
SMB1 disabled -- no workgroup available


Here 4.15:
[cn at printsrv-test ~]$ rpcclient printserver -U "cn" -c "enumprinters"
Password for [DOM-02\cn]:
	flags:[0x800000]
	name:[\\PRINTSERVER\XXX-MFP]
	description:[\\PRINTSERVER\XXX-MFP,XXXX PCL6 UniversalDriver VX.XX,XXXX 
XXXX XXX XXXX PCL X]
	comment:[XXXX XXX XX XXX PCL X]

[cn at printsrv-test ~]$ smbclient -L printserver
Password for [DOM-02\cn]:

	Sharename       Type      Comment
	---------       ----      -------
	print$          Disk
	IPC$            IPC       IPC Service (Printserver)
	XXX-MFP    	Printer   XXXX XXX XX XXX PCL X
	
SMB1 disabled -- no workgroup available


According to the Wiki some things change for 4.16 
(https://wiki.samba.org/index.php/Setting_up_Samba_as_a_Print_Server)

And we have set this with regards to spoolss:
	# for 4.15 only these
         rpc_server:spoolss = external
         rpc_daemon:spoolssd = fork
	spoolss: architecture = Windows x64
         # additionally for Samba 4.16
         rpcd_spoolss:idle_seconds=300
         rpcd_spoolss:num_workers = 10

But still no joy. No printing from Windows and no printers listed with 
RPC client or smbclient. The commands above were run as normal user. 
Running them as Administrator does also not work (min domain uid = 0 is 
set).

Anyone know where to search?
