The header for printer/punch device data can return data for local and remote printers and local and remote punches. The total length of the data for a device is accounted for by the prefix section which follows this header structure. The prefix section will also identify the type of data returned in this header. For printer/punch devices the data (section) type is JDTYPRPU.
