Select sub-report from the design pallet and drag one and only one sub-report to the detail a band that prints only once per report. For this example we'll drag the sub-report to the Report Header band. We'll take care of the others other sub-reports later. The insert-sub-report dialog will ask whether you want to insert an inline or banded sub-report. Since we want the sub-reports to print side-by-side, we'll select inline. Go to Format->Size and Borders (the keyboard shortcut is Ctrl-1) and set width to 189 and height to 72 to match the size of the labels. While you're in the Format dialog you can also alter the font settings if you wish.
