Branch Office Direct Printing

Branch Office Direct Printing can reduce Wide Area Network (WAN) usage by printing directly to a print device instead of a server print queue. This feature can be enabled or disabled on a per printer basis and is transparent to the user.
This feature requires a print server running Windows Server 2012 and clients running Windows 8. It is enabled by an administrator using the Print Management Console or Windows PowerShell on the server.
Practical applications
Branch Office Direct Printing may be able to save your organization money by reducing network traffic on expensive WAN links and by reducing the workload on busy print servers centrally located in your datacenter.
Important functionality
Branch Office Direct Printing may benefit your organization in the following ways:
Client computers running Windows Server 2012 obtain printer information from the print server, but send the print jobs directly to the printer. The print data no longer travels to the central server and then back to the branch office printer.
The printer information is cached in the branch office, so that if the print server is unavailable for some reason (for example if the WAN link to the data center is down), then it is still possible for the user to print.
The client computer renders the print job before sending it to the printer. The major difference between Branch Office Direct Printing and Client-Side Rendering (CSR) is that Branch Office Direct Printing does not send the print job to the server. Instead the job is sent directly to the printer, resulting in a significant reduction in network bandwidth usage when the printers are centrally managed.
