I have read about but not used this approach: In report design view, page setup tab on ribbon, set the page size for the report. On property sheet Other tab, set 'use default paper size' to yes. Then the report should print on the designed paper size and not the default of the printer. I believe you must be connected to the printer that has the desired size option, otherwise you would not be able to choose it from the size list.
The more we hear silence, the more we begin to think about our value in this universe.
