You have followed these instructions  , but you get this error message
Ein Treiber <Treibername>, Typ 3 -Benutzermodus, x64 konnte nicht installiert werden Das Netzwerk ist ausgelastet
(this worked in a specific environment)
If you have trouble with Windows 10 try with Windows 8.
You have to install the driver locally, before you can upload the driver to the server.
Make sure the ucr variable samba/spoolss/architecture is set properly and you uploaded the driver according to these settings first.
The basic principle: The printer driver upload is just a series of file write operations against a specially named file share.
First test: Test Linux access (if necessary also create a test file, e.g. touch testfile0) and
second test: Access via Samba
su - Administrator cd /var/lib/samba/printers/x64/3 touch testfile0
Test the samba share:
smbclient "//$(ucr get ldap/master)/print$" -U Administrator -c "cd x64/3; put /etc/hosts testfile1"
