ReportSmith page size


Can anyone help me figure out this basic problem?

I want to have reportsmith generate a report for a HP Plotter with size A2 for
presentation purposes, I also want this same report to be printed on HP
Laserjet A4. The problem is simply that I cannot get more than one A4 page
wide when page setup is set to A4, when my results are about 3 A4 pages wide.
How can I print a report that returns a result of over one page wide?
