Description: Lets the host application set up target (eg.scan) destinations. The destinations can be a host network address and/or an application to be launched on that host. The string sent down has a list of 'KEYWORD=value;' items. The data sent down also contains a string to be displayed in the device LCD display. The device POS specifies the number of strings that can be handled (eg. 20) and the replacement/expiration policy as new target destinations are added. Additional information: For push scanning on the LaserJet 1220, there will be a limitation to the number of unique strings sent to the device via UI-ADD-OPTION. A host registers for push scanning by using the UI-ADD-OPTION object. Sockeye will limit the number of hosts registered for push scanning to 20. Sockeye will have a limitation of 1. Another limitation for the LaserJet 1220 is that the DISPLAY value must be at most 18 characters. This limitation is due to the control panel display.
