Jasper Reports: How can I print multiple pages in one page - jasper-reports

Question

I am new to Jasper Reports. I have a report with 2 groups. Depending on the query, multiple pages are being printed.
1st Group Height -- 95 Points and 2nd Group Height -- 144 Points
I want these multiple pages to be printed in one page (I want to incorporate 5 pages in a page). Each page height is 239 Points. (Even if content of page is less than 239 Points, I want to keep the remaining part as blank and start the next page after 239 Points). I tried creating a Report and included the above report as a sub-report and set the height of main report as 1195 (239 * 5) Points. Still, these are being printed in different pages.
The result of export is:
The main report design is:
The first subreport design is:
The second subreport design is:
Please help me regarding this.

Answer 1

I've made a test based on your specifications and it seems to work just fine. I can give you a couple of pointers here.
In your main-report design, the height of the sub-report element doesn't matter as long as it is equal to the underlying band. If the sub-report element is shorter, the difference will appear in the result.
The page height of the sub-report doesn't matter, just the total height of the bands.
Check to make sure that the "Start on a new Page" option hasn't been selected on the groups that you have created. This is the most likely issue.
If the top 3 hasn't fixed your problem, look through the sample below and compare differences.
