I'm trying to print a text/barcode on a Zebra printer with an ASP.NET web application.

My code is:

```
PrinterSettings ps = new PrinterSettings();
ps.PrinterName = "zebra";

List<byte> page = new List<byte>();
page.AddRange(ZPLCommands.ClearPrinter(ps));

page.AddRange(ZPLCommands.TextWrite(1, 1, ElementDrawRotation.NO_ROTATION, 1, "Teste"));

page.AddRange(ZPLCommands.PrintBuffer(1));
new SpoolPrinter(ps).Print(page.ToArray());

```

The printer throws the paper but its blank.

Can you have any idea to solve this issue?

Thanks in advance.
