本文介绍如何使用Java实现两种方式的本地打印：一种是通过JasperPrint对象直接打印JasperReports报告；另一种是从字节数组创建图像并将其转换为JPEG格式进行打印。文章详细展示了如何设置打印服务、创建打印任务及文档，并提供了完整的代码示例。

//=====================调用本地打印  1 打印 JasperPrint 文件
    private void printPDF(JasperPrint jasperPrint){
        DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;
        PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
        HashPrintServiceAttributeSet psat = new HashPrintServiceAttributeSet();
        
        PrintService[] pservices = PrintServiceLookup.lookupPrintServices(flavor, aset); 
        PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();
        PrintService service = ServiceUI.printDialog(null, 200, 200, pservices,   
                defaultService, flavor, aset);
        if(service != null){
            try {
                
                PrintServiceExporter exporter = new PrintServiceExporter();
                exporter.setParameter(JRPrintServiceExporterParameter.PRINT_REQUEST_ATTRIBUTE_SET, aset);
                exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE_ATTRIBUTE_SET, psat);
                exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, false);
                exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, false);
                exporter.setParameter(JRPrintServiceExporterParameter.PRINT_SERVICE, service);
                exporter.setParameter(JRPrintServiceExporterParameter.JASPER_PRINT, jasperPrint);
                exporter.setParameter(JRPrintServiceExporterParameter.IGNORE_PAGE_MARGINS, true);

                exporter.exportReport();
                
            } catch (Exception fe) {
                logger.info("打印失败", fe); 
            }
        }else {
            logger.info("打印失败");
        }  
    }
