This is all between you, jasper reports, and your printer.
AUTOSENSE basically just pumps the data in the file to the printer port
(via GDI APIs).
Not really different than :
copy bill.html LPT1:
So you can only send via AUTOSENSE something your printer understands.
For dot matrix printers basic ASCII text with newlines, tabs etc is
probably OK
But its a bit suspicious that your file name ends with .html
I doubt there's a dot matrix printer in the world that can render HTML
directly

I have a dot matrix printer nad i want to print data directly to the dot matrix
printer. I have use the JasperReport as reporting tool but it prints very
slowly. I have also use the JRTextExporter exporter = new JRTextExporter(); for
exporting reports in text but it can't make a good alignment to the text and
event i can't do any type of formatting in the text File. My Code is
[b]public void convertToText[/b]() {
JRTextExporter exporter = new JRTextExporter();
File file = new File("C:\\bill.html");
try {
exporter.setParameter(JRTextExporterParameter.JASPER_PRINT,report.getReport());
exporter.setParameter(JRTextExporterParameter.OUTPUT_FILE, file);
exporter.setParameter(JRTextExporterParameter.PAGE_HEIGHT,new
Integer(15));
exporter.setParameter(JRTextExporterParameter.PAGE_WIDTH,new

exporter.setParameter(JRTextExporterParameter.CHARACTER_WIDTH,new
Integer(30));
exporter.setParameter(JRTextExporterParameter.CHARACTER_HEIGHT,new
Integer(30));
exporter.exportReport();
getPrinter(file);
} catch (Exception ex) {
ex.printStackTrace();
}
}
[b]public void getPrinter[/b](File file)
throws PrintException, FileNotFoundException {
javax.print.DocFlavor flavor =
javax.print.DocFlavor.INPUT_STREAM.AUTOSENSE;
javax.print.attribute.PrintRequestAttributeSet pras =
new javax.print.attribute.HashPrintRequestAttributeSet();
PrintService printService =
PrintServiceLookup.lookupDefaultPrintService();
javax.print.DocPrintJob job = printService.createPrintJob();
java.io.FileInputStream fis = new java.io.FileInputStream(file);
javax.print.attribute.DocAttributeSet das = new
javax.print.attribute.HashDocAttributeSet();
javax.print.Doc doc = new javax.print.SimpleDoc(fis, flavor, das);
job.print(doc, pras);
}
}
