ESCPOS 1.1.0

ESCPOS

A ESC/POS Printer Commands Helper

Installing via the NuGet Package

PM> Install-Package ESCPOS

Usage

All command methods will return a byte array that you should concatenate with the bytes of your data, and then send it all to your printer.

The Print extension method will send a byte array to the informed printer address, which can be something like COM3, LPT1, \\127.0.0.1\printer, etc or even a path to a text file like ./print.txt.

There is also an Add and ToBytes extension methods located in the namespace ESCPOS.Utils. The first one for byte arrays, you can use it to concatenate 2 or more byte arrays just like this:

byte[] result = array1.Add(array2, array3, ..., arrayN);

The second for strings, you can use it to convert a UTF-8 string to a byte array

byte[] result = "Some string".ToBytes();

Examples

All examples will assume the below using statements

using static ESCPOS.Commands;
using ESCPOS;
using ESCPOS.Utils;

QRCode

byte[] qrCodeCommand = PrintQRCode("Some data");
qrCodeCommand.Print("COM2");

Barcode

byte[] barCodeCommand = PrintBarCode(BarCodeType.EAN13, "9780201379624");
barCodeCommand.Print("LPT1");

Considerations

This library will only accept UTF8 Encoding for Barcodes and QRCodes data.
