将jasper报告导出到斑马打印机而不是完全打印它

Question

我有以下代码用于将发票打印到zt410-300dpi打印机：

private static void jasperPrint56(JasperPrint jasperPrint, String printerName) throws JRException, IOException {
    PrinterJob job = PrinterJob.getPrinterJob();

    PrintRequestAttributeSet printRequestAttributeSet = new HashPrintRequestAttributeSet();

    PrintServiceAttributeSet printServiceAttributeSet = new HashPrintServiceAttributeSet(new PrinterName(printerName, null));
    PrintService[] printService = PrintServiceLookup.lookupPrintServices(null, printServiceAttributeSet);
    int selectedService = 0;
    try {
        job.setPrintService(printService[selectedService]);

    } catch (Exception e) {

        System.out.println(e);
    }
    JRPrintServiceExporter exporter = new JRPrintServiceExporter();

    exporter.setExporterInput(new SimpleExporterInput(jasperPrint));

    SimplePrintServiceExporterConfiguration configuration = new SimplePrintServiceExporterConfiguration();
    configuration.setPrintService(job.getPrintService());
    configuration.setPrintRequestAttributeSet(printRequestAttributeSet);
    configuration.setPrintServiceAttributeSet(printServiceAttributeSet);
    configuration.setDisplayPageDialog(false);
    configuration.setDisplayPrintDialog(false);
    exporter.setConfiguration(configuration);
    exporter.exportReport();
}

这不会打印完整的报告，只打印约30％的报告。 在jrxml文件中，我已经定义了页面宽度和高度，如下所示：

页宽=＆＃34; 288＆＃34; pageHeight =＆＃34; 432＆＃34;

转换为72 dpi的碧玉后，其中4英寸x 6英寸

在打印机属性中，我也将页面大小设置为4x6。
