What is currently the best way to give the user the ability to designate a report-specific printer?

This is a large application where the user has the ability to add new reports.

If a DEVICE=PrinterName line is added to the Expr field in the first record of a frx, will the report always be sent to the specified printer without having to add a Set Printer To Name command?
How does that work?

Thanks very much,
Stan
