Default to print landscape from ColdFusion?

[kathkath]

There is a recordset set on a webpage that uses ColdFusion codeing to be turned into an excel file. When the user clicks on a button on the web page, it sends them an e-mail that contains the excel file (default to print portrait). Is there anyway to default the document to print landscape using CF codeing so that user don't have to change their print settings?

Thanks in advance!
