Printing to a specific printer

[Jonathan Kok]

I'd like to be able to print a document to multiple printers. For example, when I print a purchase order, I'd like one copy to print to the default printer, and another to automatically print to the accounting printer. Alternatively, I'd like to automatically print to the Fax printer when I hit the "Fax PO" button. The PrintOut command allows me to specify other particulars, but not which printer to print to. Is there any command that will allow me to do this?
Thanks,
