To have Traps reported in your account, you need to enable Traps in the HP printers JetDirect Card.

See FAQ here how to enable Traps using Telnet

This can also be done using WebJetAdmin when it is many printers.

We have also created a small tool where you easily can set trap destination in a HP printer.

You can download the tool here: http://euroform.worketc.com/?SendFile=3bac9742-c920-47c0-979c-ab340efe6624

1. Start "TrapSetup.exe"
2. Type in the IP of the PC/Server where the Data Collector is installed, ex. 192.168.14.63
3. Type in the IP of the Printer where you want to enable Traps, ex. 192.168.100.122
4. If you click "Show current Trap Destination" then you will see if a Trap Destination is set.
