Add a Back (Close) button to the Print management dialog/screen.

Clicking the Back button should:

• save any updates made on the Print management screen
• return the user to whichever parameter screen they opened the Print management screen from

At the moment, Back / Save buttons are not present on the Print management screen. At the moment, the only way to close the Print management screen without navigating away is to press the Esc key, but there is no on-screen indication that this is possible.
