Typically, if a device is using passthrough to communicate with a target system, the target system will purge all knowledge of the device when the session is ended. In the case of printers, this could create problems since many programs may be still creating output for the printer at the time the session is ended. Also, programs may need to create output for the printer even when it is not communicating with the target system. This technique provides a solution to this problem particularly by not purging the information when the session terminates; instead, a specific operator request is required to delete the information. This may be used as part of the implementation of PC (IBM Personal Computer) Support/36 Workstation Feature for the S/36 (IBM System/36 computer).
