I am working with an Hp8150 with the optional 7 bin mailbox attachment. I was wondering if this type of hardware would affect the licnensing.

Hi,

What you should under "Installed Devices" of the Status Page is any storage device installed on the printer.
Example: Hard disk or Flash memory.
You should see something like this: %disk0% along with the size information and space available.

Options such as duplexer and other Paper handling could appear under the Paper Handling section of the Status Page.

What could influence the activation code is any hardware or maintenance change on the Printer.

Hope this helps.

Thanks
Cosimo
