Barcode Printing Sato LM408e c#

Question

I'm making an application that produce barcode labels. I'm using Sato LM408e thermal printer. In order to print I'm using sbpl command. I got no error, but the printer doesn't print anything. Is there anyone who has experience printing with sato barcode printer? lm 408e to be more specific

My Code:

PrintDialog printDia = new PrintDialog();
printDia.PrinterSettings = new PrinterSettings();
DialogResult result = printDia.ShowDialog();
StringBuilder sb = new StringBuilder();
        sb.AppendLine("<STX><ESC>A");
        sb.AppendLine("<ESC>H0001<ESC>V0001<ESC>XM45676567");
        sb.AppendLine("<ESC>Q1");
        sb.AppendLine("<ESC>Z<ETX>")
String output = sb.ToString().Replace("<ESC>", ((char)27).ToString());
        output.Replace("<STX>",((char)2).ToString());
        output.Replace("<ETX>", ((char)3).ToString());
if (result == DialogResult.OK)
        {
            RawPrinterHelper.SendStringToPrinter(printDia.PrinterSettings.PrinterName, output);
        }

My string output:

Answer 1

String.Replace returns a new instance, it does not modify the original string.

((char)3).ToString() is "3", you need "\x3".

So, try this:

String output = sb.ToString().Replace("<ESC>", "\x1b").Replace("<STX>","\x2").Replace("<ETX>", "\x3");

Answer 2

I use CL4NX, CL408e, and GL408e label printers except I print labels that are in Non-Standard SBPL (but it's not that much different than standard).

Since nothing is happening, the first thing I would check is that the printer is online and connected properly. You can use the SATO All-In-One Tool to help you with this. Is the printer connected directly to the machine you're trying to print from or is it a network share?

I would also look at your code, as I'm not sure you need the STX and ETX with SBPL by default. Try printing without them and see if it makes a difference.

Lastly, I would check your Dipswitch settings (LM408e Manual). I've had problems like yours before where it took me a while to realize that the Dipswitch settings weren't as they should be.

You cannot send ESC (hex 1B) or STX (hex 02) in plain text. SBPL uses binary data. Try this:

sb.AppendLine("\02\1bA");

... and so on.
