I haven't got a printer, no real need for one, so for testing purposes
I added these lines to the bottom of a smb.conf on a DC running 4.19.4
from Debian bookworm backports:

[print$]
   comment = Printer Drivers
   path = /var/lib/samba/printers
   browseable = yes
   read only = yes
   guest ok = no

[lp1]
        comment = LP1 Printer
        path = /var/tmp
        printable = Yes
        browseable = Yes
	printer name = Cups-PDF
	public = yes

When I ran 'samba-tool testparm', I got this back:

[print$]
	comment = Printer Drivers
	path = /var/lib/samba/printers

[lp1]
	comment = LP1 Printer
	guest ok = Yes
	path = /var/tmp
	printable = Yes
	printer name = Cups-PDF

As expected, all the default lines had been removed.

This is the output from smbclient:

smbclient -NL localhost
Anonymous login successful

	Sharename       Type      Comment
	---------       ----      -------
	sysvol          Disk      
	netlogon        Disk      
	print$          Disk      Printer Drivers
	lp1             Printer   LP1 Printer
	IPC$            IPC       IPC Service (Samba 4.19.4-Debian)
SMB1 disabled -- no workgroup available

Started W10 in a VM, opened explorer, no sign of the DC, back to the DC
and installed wsdd, back to W10 and there was the DC in explorer and
when I clicked on the DCs icon, it opened and there was lp1.

Thank for your test, but ...

The printers added manually into smb.conf are always show and work also
in RH and Arch Linux when this problem under analysis and still unknown
occurs. 

On these for now 2 systems only the CUPS shared printers, included via
[printers] session, are not shown in some cases.
