A symbiont is a piece of software that transfers data to be printed to an output device. OpenVMS provides a standard print symbiont named PRTSMB which prints files on hardcopy devices. Other examples of symbionts include TELNETSYM, LATSYM, NULLSYM and others including user-written symbionts. Symbionts are stored as .EXE files in SYS$SYSTEM and are specified when creating a print queue.
