Post Thu Mar 08, 2012 3:23 am not triggering

Hi all!
I just downloaded OpenTPV, a fork of OBPOS 2.1, i have a problem: the code it´s not triggering the event at all, i´m adapting the "kitchen/bar" example to be able to print from 2 different printers (kitchen and bar).
Does anybody know any reason for this?
Thank you all in advance!
