a report which uses every millimeter of an A4 pageSo this seems to be the basic issue.
uses every millimeter of an A4 page...you may wish to consider redesigning the report to not be so "confined"
Further reduction is not relevant.These two statements are conflicting...
It could possibly be reshaped to suit Letter,
Unless you have exactly the same printer and driver setup, you may see minor differences in output.
So the first question is, does the current printer/driver being used support the A4 page size?
