I am trying to start working with ESC / P commands with a Brother QL-800 label printer. I have tried the printer software, P-touch Editor 5.0, and if I can print the labels that I want, the printer works fine, but, when it comes to making my own Java code labels, the printer does not work at all, does not respond What can I try now?
This is the code I use. What am I doing wrong?
public class PrintESC_P {
public static void main(String[] args) {
PrintService printService = null;
String printerName = "Brother QL-800";
HashAttributeSet attributeSet = new HashAttributeSet();
attributeSet.add(new PrinterName(printerName, null));
PrintService[] services = PrintServiceLookup.lookupPrintServices(null, attributeSet);
if (services.length == 0) {
throw new IllegalArgumentException("Printer not found.");
} else if (services.length > 1) {
System.out.println("Found more than one printer. Only the first printer will be used.");
}
printService = services[0];
System.out.println("Printer found: "+printService.getName());
try {
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
String _ESC_P_Code = "ESC i a 00h\r\n" +
"ESC @\r\n" +
"ESC i L 01h\r\n" +
"ESC ( C 02h 00h FCh 02h\r\n" +
"ESC $ 2Bh 00h\r\n" +
"ESC ( V 02h 00h 6Dh 01h\r\n" +
"ESC k 0bh\r\n" +
"ESC X 00h 64h 00h\r\n" +
"PRINTER TEST\r\n" +
"ESC i C\r\n" +
"FF\r\n";
SimpleDoc doc = new SimpleDoc(_ESC_P_Code.getBytes(), flavor, null);
DocPrintJob job = printService.createPrintJob();
job.print(doc, null);
} catch (Exception e) {
e.printStackTrace();
}
}
}
