[Samba] Almost all print driver uploads fail

[Ingo Asche]

Hi,

I might have an idea: Can you have a look in the printer mangement of 
your print server from the Windows side?

In the driver section there should be a column "package". I presume the 
Kyocera driver has there a "true" present and all other printer drivers 
a "false"?

Then this should help you:

I have another link, too, but it is in German:
