I don't think you remember correctly ;). From man smb.conf I

Any way I have installed a new samba server and a new printer on the 
server. From a 64bit client I have installed the 64 and 32 bit drivers 
and all seems to works correctly: on the server I can find the drivers 
installed in <path option in print$>/x64/3 for the 64bit version and 
<path option in print$>/W32X86/3 for the 32 bit version.

If I double click on the shared printers from a 64bit client I get the 
error: "A policy is in effect on your computer which prevents you from 
connecting to this printer queue".

If I double click on the shared printer from a 32 bit client the printer 
seems to be installed correctly but when I go to the printer properties 
I get the message that the printer driver is not installed and if I want 
install a new one. On the logs I can find:
> [2020/10/30 11:23:17.823375,  0]
../source3/smbd/trans2.c:3447(smbd_do_qfsinfo)
>   smbd_do_qfsinfo: not an allowed info level (0x102) on IPC$.
If I choose to install a new driver and I choose the same 32bit version 
of the driver the system says that it is not possible to install the driver.

:?

You have to set a GPO, 'Restrizioni di selezione e stampa' in italian.

Could be a driver bugs. Try to:

a) retry some time subsequently; some driver need that you try 2-5
  times to load correctly the driver (but seems that samba load the
  driver without error, indeed)

b) change driver (also, driver revision could help)

c) if the driver come with some CAB file, unpack it in source driver
   folder before uploading; this is sometime needed for language
   specific file (so, unpack italian only cab).

d) last resort, but sometime works, load the driver/printer in a
   windows machine, the 'copy' the driver via rpcclient:

ooops, you are right, I have forgot to add this new server to the list 
of allowed point and print server. Any way even adding this policy 
change only the error shown. Now the error is: "The printer driver is 
not compatible with a policy enabled on your computer that blocks NT 4.0 
drive"...

Looking for a solution of this problem I found that removing 
C:\windows\system32\spool\drivers\x64 the printer is installed successfully!

I'm not sure but seems that troubles on win64 OS has been solved.

Now the drive on the samba server seems to be installed correctly. Win7 
64bit (and I hope Win10 64bit too, I haven't try it yet) and Win7 32bit 
clients can install the shared printer double clicking on it and all 
seems to works flawlessy now. Remain a problem on WinXP 32bit clients: 
if a WXP32 client double click on the shared printer all seems to works 
and the printer is installed flawlessly but when I try to print 
something to the printer I get an error and if I go to the properties of 
the printer windows says that the driver is not installed. That's happen 
only after upgrading the samba domain to AD. The driver is the same that 
was working perfectly before the domain upgrading... why XP says that 
the print driver is not installed?
There is another very strange behavior that I think it is be tied to. If 
I go in winxp 32bit to the properties of the shared printer installed 
and I say "no" when ask to install the driver and then in advanced tab
I
select to install a new driver and I follow the procedure selecting the 
same 32bit driver the dialog show a summary saying: "HP Universal 
Printing PS, x64, Windows XP". But winxp is 32bit and I have select a 
32bit driver: why says x64?!?

...I'm very confused :(
