if you cant find the events then you can use vce to set the print bricks id and maybe even the name
e.g onactivate - self - vcemodvariable - brick [printID] set [12]
2000 onactivate - self - vcemodvariable - brick [printID] set [13]
i've not tried this before but you're probably able to set the printname of the brick as well e.g
onactivate - self - vcemodvariable - brick [printname] set [abcd]
you're gonna have to find the ids and the names of the prints by setting the brick to the print and using
onactivate - centerPrint - <var:br:printID> <var:br:printname>
