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.
ClickOnce Software Installation and Launch
The following events occur when you start the Smart Client installation and launch:
1. Client using Internet Explorer browses HTTP service (URL: http://server:8000).
The server detects Microsoft .NET Framework on the browser client.

2MB les are downloaded through the HTTP service.

3. Microsoft .NET Framework Remoting begins and uses port 4088.
For the rst run, 50 MB les downloaded.
The HP logo page is visible.
The client les are updated if a newer version is detected.
4. HP Web Jetadmin Client application is started.
The client begins detecting events, executing calls, and more.
The help content traverses the HTTP service.
All other client communication uses .NET Framework Remoting.
