iReport - Limit number of records allowed in a sub report - jasper-reports

Question

I am trying to create a report that will be used for check printing. Its layout is stub, stub, and then check. I thought the best way to do this would be have the detail for the stubs be a sub-report (inserted twice on the report) and the normal detail of the report for the check info. A 3rd party device will handle the "check" base on the info I pass in on the report in that detail band (printing account info for the micr part of the check, adding a signature and some anti theft "stuff").
The problem is I can't figure out how to limit the number of records on the sub-report. I have tried setting the height in the master for the band, in the master for the sub-report property, and on the sub-report for the height of the report. Nothing seemed to work. I also tried to do something like.
($V{REPORT_COUNT} %15) == 0
Now I am not a Java guy. We use jasper reports for form generation in or python based ERP system.
Any suggestions on how I should go about designing this report? Also to note the "check" part of the report would need to have void details on all pages except one.
Edit
For example, lets say that we pay vendor FOO for 35 invoices. The layout is going to be stub, stub, check (each a 1/3rd the size of the page). Stub 1 and stub 2 are identical copies of each other. So page one would show 15 invoices in stub one and then show the the SAME 15 invoices in the next stub, and then it would print the physical check details on the bottom 3rd of the page. Page 2 would show the next 15 invoices (same layout as above) but the check details are VOIDED. The last page will show the remaining 5 invoices.
The pages are perforated. We keep 1 stub, and then send the check stub to the vendor.

Answer 1

Try
$V{REPORT_COUNT} == 15+(($V{PAGE_NUMBER}-1)*15)
in the Print When Expression of the break in the subreport detail band.
