Printing on environment where NTLM is denied

Hi,

One of customer I support, they told me that they are deny all NTLM traffic on their network. They were asking me how this will impact the printing services, since we use IP instead of hostnames.

With printing they access the printer configuration via http using IP and also have the print server ports are configured via IP.

I am unsure how disabling NTLM will impact and environment that uses IP to access devices.

I did find this note https://technet.microsoft.com/en-us/library/jj865671(v=ws.10).aspx, but to me I am not sure how to understand the access bases on Ip section..

Are you able to bring some light?
