[cups] Using CUPS client with Windows Print Server

Wed Jul 5 15:19:32 PDT 2017

I do not know how wise or unwise this may be but I am having luck using Windows print servers using LPD.

I defined the printers to Oracle Linux 6.9 using the following syntax:

lpadmin -p <local printer name> -v lpd://<domain name of Windows print server>/<Windows shared printer name>

We just moved the application from Solaris 10 servers to Oracle Linux 6.9 servers about 2 months ago and I wanted to keep the application changes to a minimum.  We do not do a lot of printing but this is working well for us.

HTH,
Glen

Subject: [cups] Using CUPS client with Windows Print Server

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,
Prentice
