DirectPrint: printing no longer has its own entry in the left menu. Each person finds their computers and print jobs in their own profile, under Printing.
DirectPrint: administrators have a new page in Settings → Apps → DirectPrint showing everyone on the team, whether they can print, their computers and printers, and every print job. From there an administrator can allow one person to print, ban them (their computers are disconnected at once), or disconnect any computer.
