Hello Steve,

Adagio OrderEntry 9.3A (2017.12.04) has enhanced options for selection:
Print functions for Order Confirmations, Picking Slips, Invoices, Credit Notes and RMAs if used allow you to select and send/print to multiple Send Methods (Printer, PDF, Email) simultaneously. The Print, Email, ePrint and Fax buttons on print dialogs have been replaced with a single button called Send/Print. Allows you to quickly print and email a document in one operation.

OR... you can select the option to 'Match preferred send method' for Order Confirmations, Invoices, Credit Notes and RMAs.
