with reference to the figure , there is illustrated one preferred embodiment for use of the concepts of this invention . the figure illustrates method 2 for employing device identification dependent rendering jobs . method 2 includes , in part , the steps of : determining a desired imaging device upon which a document is to be rendered ( step 4 ); encoding a header of the document to designate the desired imaging device ( step 6 ); scanning the header to determine the desired imaging device ( step 8 ); forwarding a document to the desired imaging device ( step 10 ); and rendering the document on the desired imaging device ( step 12 ). it is to be understood that the flowchart of the figure shows the architecture , functionality , and operation of one implementation of the present invention . if embodied in software , each block may represent a module , segment , or portion of code that comprises one or more executable instructions to implement the specified logical function ( s ). if embodied in hardware , each block may represent a circuit or a number of interconnected circuits to implement the specified logical function ( s ). also , the present invention can be embodied in any computer - readable medium for use by or in connection with an instruction execution system such as a computer / processor based system or other system that can fetch or obtain the logic from the computer - readable medium and execute instructions contained therein . a “ computer - readable medium ” can be any medium that contains , stores , or maintains programming for use by or in connection with the instruction execution system . the computer - readable medium can comprise any one of many physical media such as , for example , electronic , magnetic , optical , electromagnetic , infrared , or semiconductor media . more specific examples of a suitable computer - readable medium would include , but are not limited to , a portable magnetic computer diskette such as floppy diskettes or hard drives , a random access memory ( ram ), a read - only memory ( rom ), an erasable programmable read - only memory , or a portable compact disc . with respect to step 4 , the desired imaging device can be , but is not limited to , a printer , a printing device , a multi functional product ( mfp ), a photocopier , a facsimile machine or the like . it is to be understood that the user will select a desired imaging device such that only that particular imaging device will be allowed to render the print job . with respect to step 6 , a document to be rendered by the desired imaging device is conventionally prepared on a document processing device , such as a word processing device or other such suitable computing device . a document header is conventionally inserted into the document . a document header , typically , refers to a text area located near the top of the print job document that may contain , among other things , data related to message type and priority status . also , the header can be encoded with an identifier ( id ) such as a particular printer model number , formatter id of the desired imaging device , a firmware version , an internet protocol ( ip ) domain address , a subnet mask , vendor id ( specific brand ), reseller id , imaging device class ( print vs . fax ; color vs . monochrome ) or any combination of similar unique identifiers . also , the id can be encoded with an encryption code or other such similar protection devices . it is to be understood that the nature of the id is that it will allow only those imaging devices set forth in the header to render the print job . in this manner , the user encrypts the header with the id of the desired imaging device . with respect to step 8 , the header is conventionally scanned by a computing device in order to forward the document to the desired imaging device . with respect to step 10 , after the header has been conventionally scanned , the document is conventionally forwarded to the desired imaging device . it is to be understood that during this step , the document processing device can , for example , contact or ping all the imaging devices which the document processing device is capable of sending documents to be rendered . the document processing device conventionally interacts with all of the imaging devices to determine which imaging device is associated with the unique id located in the header . finally , with respect to step 12 , the document is conventionally rendered by the desired imaging device . the efficacy of the present invention will now be discussed . the present invention is advantageous because it allows the user to specify only certain particular imaging devices that can render this particular print job . for example , a confidential print job is created by the user and stored in a print ready format on the user &# 39 ; s printer with the printer identifier ( id ) included in the header of the print job . if , at a later time , an unauthorized user attempts to hack or break into the user &# 39 ; s printer that was rendering the confidential print job , the unauthorized user would be unable to print the confidential print job on another imaging device . this is because the printer id located in the header of the confidential print job would contain the id of the user &# 39 ; s printer . therefore , no other imaging device would accept the confidential print job . although the flowchart of the figure shows a specific order of execution , the order of execution may differ from that which is depicted . for example , the order of execution of two or more blocks may be scrambled relative to the order shown . also , two or more blocks shown in succession in the figure may be executed concurrently or with partial concurrence . all such variations are within the scope of the present invention . once given the above disclosure , many other features , modifications or improvements will become apparent to the skilled artisan . such features , modifications or improvements are , therefore , considered to be a part of this invention , the scope of which is to be determined by the following claims .
