The first shot on target came from the visitors after nine minutes when Clayton Donaldson brought a great save out of Adam Collin.
Rotherham doubled their lead a minute before the break. A brilliant passing move down the left involving four players ended with Pringle squaring the ball across the edge of the area for Agard to slam home his 20th goal of the season.
Agard almost completed his hat-trick after 59 minutes, but headed just over the crossbar before Lee Frecklington saw a great curling shot go just wide of the upright after 73 minutes.
Substitute Harris Vuckic added the third goal in added time one minute after stepping off the bench.
