Re: print a large # of different pages eg. 1,301 2,301 3,301 and so on (301 is back side)

I have found this:  (i am now trying to print from a pdf with 90 pages) - somehow it adds one to the page no.

var pp = this.getPrintParams();

pp.interactive = pp.constants.interactionLevel.full;

pp.printRange=[[1,89],[2,89],[3,89]];

this.print(pp);

Result:

1,89,2,89,3,89

which gives         2 - 90 ; 3 - 90 ; 4 - 90  in acrobat's print dialog box!  Why?
