Interposer device type - manufacturer independent. An 'xcmHrDeviceInterposer' device is an input device which physically resides downstream of the print engine amongst finishing modules. An 'xcmHrDeviceInterposer' device with 'xcmHrDevInfoRealization' of 'physical' is a 'real' input device (eg, a 'high-capacity Interposing feeder' that physically resides amongst finishing modules on a high-end printer). An 'xcmHrDeviceInterposer' device with 'xcmHrDevInfoRealization' of 'logical' is a 'virtual'

input device (eg, a 'personality' of a 'high-capacity Interposing feeder' that physically resides amongst finishing modules on a high-end printer). Interposers are essentially feeders that are placed downstream of the print engine paper path and upstream of finishing devices. Interposer fed media is not marked by the print engine; instead media fed from an interposer is inserted before, between or after marked pages. The media constitutes covers, separators etc.
