Printing attachments

I wish to create an 'action' that will print all the attachments. For now, I'll focus on ONE attachment.

I can have a "/Launch /Win" that names an external file and calls for Windows to print it.

I can do an ExportDataObject on an attachment, and get a DOC file opened in Word, for instance.

I need to combine these: create a temporary file containing the attachment data (without prompting the user) and launch it to print.

Is this possible?
