A printing device (10) such as a laser printer includes a radio frequency controller (38) which permits the detection and redirection of media having one or more defective radio frequency device tags, such as an RFID tag, to a specific one of two or more output options (50, 52). The radio frequency controller (38) may include radio frequency control logic (500) that communicates with the base printer (10) and the output options (50, 52) over a down port (506) and up port (508) to intercept commands from the printer (10) to the options (50, 52) and to also respond to such commands. A defective tag can be detected by attempting to program a tag using an RF reader/programmer (504).
