[Samba] Print server not loading drivers

Hi List,

I'm working on setting up a print server using Samba 4.13.13 for Debian. I
have the DC running in another VM, and the print server (PS1) is joined as
a member server. I have the printers loaded in CUPS, and followed the
config guide from the Wiki. I have set the Group Policy to trust the FQDN
of this print server, and to allow the printer to install without UAC

When I browse to \\PS1.example.com, I can see all the printers listed.
Good! I move on to the Print Management step.

I load up the FQDN of the server, add the driver (a Type 3 x64 Windows 10
driver, matching my machine), all good. When I go to Properties of the
Printer, I choose No, go to Advanced, choose the driver, and hit OK.
Normally, it'd install the driver and I could start configuring it. What's
happening now is I get a message "The 'KONICA MINOLTA 368SeriesPCL SP'
printer driver is nto installed on this computer. Some printer properties
will not be accessible unless you install the printer driver. Do you want
to install the driver now?". If I choose No, I don't get to configure much
on the printer - the name and a few other things. If I click Yes, I go
through the Add Driver wizard, selecting the same driver, installing it,
then I get the same basic printer properties dialog as if I said No.

I tried the rpcclient commands listed at the bottom of the Print Server
wiki, and confirmed the driver does show up:

        description:[\\LOCALHOST\DUCH-Counselling,KONICA MINOLTA
368SeriesPCL SP,Konica Minolta bizhub 308]
        comment:[Konica Minolta bizhub 308]

I am a member of the Domain Admins group while doing this, and verified I
have the SeDiskOperatorPrivilege and SePrintOperatorPrivilege on the print
server. What am I missing? (Yes, I rebooted both client and server)

Here is my smb.conf:
