 * This class is intended to be used as base class for customized print dialog page. One of
 * the feature of the TDE print framework is to allow to customize the print dialog to
 * add some application specific print options. This is done by subclassing KPrintDialogPage
 * and reimplementing the 3 virtual functions getOptions, setOptions and
 * isValid(). The print options will be stored in the KPrinter object, and will be
 * accessible via KPrinter::option(). The option name should follow the form
 * "kde-appname-optionname" for internal reasons.
