When printing a summary by filtering from Invoices in the Navigation pane, the allocation of column widths seems to favor ID and Client/Project and not give enough to Currency. (See attached png.) Switching from Portrait to Landscape in Print Setup keeps the last 4 columns the same and gives more width to ID and Client/Project.
Re-allocate column widths by taking from ID and Client/Project and giving a little more to Cur.
