A method for virtual end nodes indicates in routing information that the data packet is for a \u201cspecial access\u201d to an end node with a virtual address. The clock generator generates a first clock signal. The ink ejector is operable to cause ejection of ink from the nozzle and resupply of ink to the ink chamber from the ink supply channel, and incorporates a movable paddle having a non-planar profile configured to control the flow of ink between the ink chamber and the ink supply channel during ejection and resupply. 0% or less, which is determined by X-ray diffractometry, a nitrogen atom-to-carbon atom ratio of 0. In some embodiments, if the target electronic document does not correspond to the library-stored electronic documents, the method includes providing-link information for user access to the target web page.
