Background Tasks: Many features in HP Web Jetadmin can be launched automatically or manually by a user
logged into a client application session. In either case, these can become background tasks that can be run
without a user being logged into a client application session. Background tasks are managed centrally by
HP Web Jetadmin software and the user can display them at any time through a task manager interface.
The Active Tasks task module is one way users can view running tasks.
HP Web Jetadmin Client
Users gain access to HP Web Jetadmin through a local Microsoft .NET Framework client application. The client
application runs on any supported client desktop. The rst time a client application accesses the
HP Web Jetadmin server, HP Web Jetadmin installs client les and launches a Windows client session. The client
session communicates with HP Web Jetadmin on the server. Client application les are left in the users’ Local
Settings directory and updated as needed. The server and client applications can run on the same host or on
dierent hosts.
