/**
* <p>The PrintServices class is an example of how to use JDK 1.4+ print
* services with ICEpdf. The example first finds printers available to the
* client machine and asks the user which one they whish to print to. Once the
* user enters their choice the printing process is started.</p>
* <p/>
* <p>As of ICEpdf 3.0 the PrintHelper class was implemented using print
* services. This examples show how the to configue and print using the
* PrintHelper class. Gernally the page settings are defined with the page
* constructor followed by a call to printHelper.setupPrintService(...) to
* setup the printing job. The Print helper can be used in a headless mode
* or in a GUI.</p>
* <p>A PDF documents full path must be specified when the application starts.
* The following is an example of how the applications is started</p>
