The Co Antrim man said Hearn's attitude is that "the players don't really matter, so **** the players", after his first-round win in the UK Championship.
Allen was referred to the World Professional Billiards and Snooker Association's disciplinary committee.
In a statement released on Thursday, the WPBSA said: "Mark Allen has been fined £250 and warned as to his future behaviour by the disciplinary committee of the WPBSA.
"This was for swearing at a live press conference during the williamhill.com UK Championship in York in December 2011."
Allen went on to reach the final of the tournament but was beaten by Judd Trump.
