[cups] Using CUPS client with Windows Print Server

Wed Jun 28 13:54:52 PDT 2017

Hi,

I've setup CUPS servers and clients in the past. On the clients, I'd 
create a client.conf file with a single line: the ServerName directive 
which specified the name of the CUPS server.

I'm now in an environment where we have a lot of Linux servers and 
workstations, but our main print server is a Windows Print Server 
running IIS/8.5. Our existing Linux systems all have their own CUPS 
server setup which duplicates the printers setup on the Windows Print 
Server. This is a lot of duplicate effort.

I'd prefer to just use the Windows Print Server, since  it supports IPP, 
which I've asked the Windows Admins to enable. That way, someone else 
can manage the printers for me. ;)

After having IPP enabled on the printer server, I created a client.conf 
file with the appropriate ServerName setting. After doing this 'lpstat 
-a' just hangs. An inspection of  the network traffic between the client 
and server shows that the server keeps informing the client that the 
object has moved:

It appears that the client is trying to access the printer at the wrong 
path. Is there any way to get a CUPS client to work with Windows Print 
Server/IIS?

Thanks,
