A method for establishing two-way communications between a host system and a device when the address of the device is initially unknown. The host system submits a job to a device with the job including address and other information required for the device to respond with the device's address. Once the host system has the device address, the host system and the device can establish bi-directional communications. In a print job, a print job language (PJL) command known as SOCKETPING is used to transmit the information between a print client and a printer. The SOCKETPING command includes fields for host system address family, protocol, address, and port as well as extensions to define job status reporting parameters. The printer responds to the SOCKETPING command with the necessary address information for the printer and job status reports as specified in the SOCKETPING extensions.
In a network system, a method of establishing two-way communication between a host system and a device wherein one-way job submission communication between the host system and at least one device has been provided, the device address being initially unknown, the method comprising the steps of:
In a network system, a method of establishing two-way communication between a print client and a printer wherein one-way job submission communication between the print client and at least one printer on the network system has been provided, the printer address being initially unknown, the method comprising the steps of:
