so this means that this actually gives me what I asked for:
var pp = this.getPrintParams();
pp.interactive = pp.constants.interactionLevel.full;
pp.printRange=[[1,1],[89,89],[2,2],[89,89],[3,3],[89,89]];
this.print(pp);
1,1,89,89,2,2,89,89,3,3,89,89
This is the result in the print dialog box: 2 ; 90 ; 3 ; 90 ; 4 ; 90
