samba - Jan 2016 - No Printer Connection, Samba sharing cups printer

Hello!

I'm using samba to share printers from a cups service. In the windows
explorer both printers, a network tcp/ip printer connected using a jet
direct box and a pdf printer added by the package cups-pdf, are visible and
both can be used from the cups web interface and work.

When trying to use each from the windows explorer:

The pdf printer can be printed to just fine.
The jet-direct printer replies with an error message after windows tries to
connect with:

[Window Title]
Add Printer

[Main Instruction]
Connect to Printer

[Content]
Windows couldn't connect to the printer. Check the printer name and try
again. If this is a network printer, make sure that the printer is turned
on, and that the printer address is correct.

[OK]

Only similar error I found is this:

running
rpcclient localhost -Nc enumprinters

returns:

and it is as the bug reproduction says : "The "name" field show
that the
printer name is missing and only the hostname appear."

I'm running samba version: Version 4.1.17-Debian

Can someone give me some advice how to fix this please?
