Example 1 with SunPrinterJobService

use of sun.print.SunPrinterJobService in project jdk8u_jdk by JetBrains.

the class RasterPrinterJob method print.

public void print(PrintRequestAttributeSet attributes) throws PrinterException {

         * In the future PrinterJob will probably always dispatch
         * the print job to the PrintService.
         * This is how third party 2D Print Services will be invoked
         * when applications use the PrinterJob API.
         * However the JRE's concrete PrinterJob implementations have
         * not yet been re-worked to be implemented as standalone
         * services, and are implemented only as subclasses of PrinterJob.
         * So here we dispatch only those services we do not recognize
         * as implemented through platform subclasses of PrinterJob
         * (and this class).
