The first thing that Windows 7 / Windows Server 2008 administrators’ll notice is that the “Print Services” role has been renamed to “Print and Document Services” to reflect the addition of the Distributed Scan Server role service. New features and Improvements have been introduced in the areas of: Reliability, Administration and Management, Performance, User experience, XPS Printing. In terms of Reliability, the main new feature is Print Driver Isolation (also referred to as “sandboxing”). This feature allows you to isolate print drivers from one another to prevent a faulty driver from bringing down the entire printing subsystem. For administrators, there’re new enhancements in the Print Management Console – not just the ability to manage Print Driver Isolation, but also the ability to create more robust custom printer and driver filtering, and some new security settings features. PrintBRM has also been improved to offer better error handling and reporting as well as other enhancements.
