Abstract: A wireless communication protocol for print by reference operations initiated by a portable wireless device. The protocol allows a portable wireless device, such as a handheld personal digital assistant, to initiate a print job with a printer by indicating the nature of the communication as a print by reference operation and identifying a location including print content. The protocol is preferably used as the body of an Object Exchange (OBEX) packet in a Bluetooth RF communication initiated by the portable wireless device with a Bluetooth capable print device, e.g., a printer or multi-function peripheral with a print capability. A preferred embodiment of the wireless communication protocol uses the body of an OBEX packet communicated by Bluetooth RF to include a tag identifying a packet body as being a packet body for a print by reference operation and a location identifying the location of the print content. With a preferred extensible mark-up language format, the location comprises an attribute.
