Ok, so we need to pass a Command Value from the Widget as well.
You need to edit your Template so we can assign the Ticket Id to a Custom Field. We will name this Custom Field TID.
Then we can pass that Custom Field as the Command Value along with the Command Name from the Widget.
So in your Printer Template, add the following so that it will assign the {TICKET ID} to the TID Custom Field:
(TID={TICKET ID})
And in the Task Complete Commands section of the Task Editor Widget we will pass the TID along with the Command.
The syntax to pass a value with the command is:
CommandName:CommandValue
... or ...
CommandName:[CustomFieldName]
So we will use this:
Listo:[TID]
Now in your Rule, the [:CommandValue] will contain the value stored in TID, which is the Ticket Id.
