Explanation:

As you are not printing to your default printer you will need to specify the printer via the d option.
The p option is used to enable notification when the print job has completed. See man page extract below. None of the answers given are correct.
The answer should be lp dprinter2 file1
-p Enables notification on completion of the print request.
Delivery of the notification is dependent on additional software.
