Electronic Surface Single API interface _java invocation Example

the electronic surface is a kind of logistics service that print and output paper logistics form through thermal paper. The print speed is 4~6 times faster than the traditional needle printing speed by using the heat-sensing display text . Electronic form embedded in the form of the interface to their own systems, websites, you can operate on their own platform to print electronic form.

At present, electronic surface single interface types are: Express Company to provide their own interface, rookie electronic surface single interface, express bird electronic surface single interface. rookie electronic Surface single interface, express bird electronic Surface Single interface access method is similar, all support 15 Express query, in which rookie does not support shun Fung electronic surface print, express birds do not support daily, fast and other express electronic surface single printing. The following is an example of the Java access for the Express bird electronic Surface single interface, which is followed by an introduction to other interfaces in other languages.
