print group in two columns but do not break page for new group

[vid.ogris]

Hello

Using iReport 5.smth, I have the following question.
I want the groups to be printed in two columns side by side. I already chech print group in new column, but it only prints two groups per page. I want all groups to be printed on one page 

Example

Group1                      Group 2 
  detail 1                        detail 1
  derail 2                        detail 2

Group3                      Group 4
  detail 1                        detail 1
  derail 2                        detail 2

.......
....
..

Now when printing group3 and group4 , they are printed on new page. I do not want it to break page

any suggestions??

thank you

best regards
