What is the purpose of the 160GB external hard drive accessory on the HP DesignJet T7100?

A.
It copies files from a PC and stores them on the printer’s internal hard drive for printing at a later
time.

B.
It replaces the printer’s internal hard disk as the repository of personal data. Therefore, the
external hard disk can be removed from the printer to store it in a secure place.

C.
It moves files from the internal hard disk of one printer to the internal hard disk of another
printer.

D.
It doubles the capacity for storing files. This gives you a total of 320GB of data storage including
the internal hard disk drive.
