How to print multiple columns in a report
Firstly, you need to work out how many columns you need and whether they will fit
onto the page. Then open the report in Design View and select FILE, PAGE SETUP,COLUMNS. For Grid Settings, enter the number of columns you want, the amount of space between rows and in the Column Spacing text box enter the amount of space you need between columns. For Column Size enter the column Width and then the Height of the detail section of the report. In Column Layout you can choose Down,
Then Across which will produce horizontal columns, or Across, Then Down which will
produce a layout similar to mailing labels. Then select PAGE, and under Orientation
choose either portrait or landscape. Click OK.
Hope this helps,
