Abstract: This invention discloses a method and system whereby a conventional electronic mail system is enhanced to add functionality to allow the sender of an e-mail message to insert a “print-on-receipt” (P-O-R) flag or code in an e-mail message and for the receiving e-mail system to detect the flag and print the e-mail without any user intervention. In the preferred embodiment, the receiving e-mail system composes and sends a affirmative feedback reply message to the sender to indicate that the original message was successfully printed. Further enhancements are described to add functionality to control the acceptable message sizes and to filter and control the processing of incoming of P-O-R e-mail to avoid unwanted messages being printed without user intervention. Further enhancements are described to print files attached to the P-O-R e-mail message.
