Diagraph IJ Printer Demo

This is a simple C# program for interfacing with a Diagraph IJ Printer using the Diagraph-IJAPI library. It demonstrates how to search for IJ printers on the network, connect to one, retrieve device information, and interact with the printer.

Prerequisites

Before running this program, ensure you have the following prerequisites:

• Diagraph IJ Printer
• .NET SDK installed
• Diagraph-IJAPI NuGet package (e.g., Diagraph-IJAPI.1.0.2.nupkg)

Getting Started

1. Create a new C# project in your preferred development environment.

2. Add the Diagraph-IJAPI NuGet package to your project.

3. Replace the default code in your project with the provided code.

4. Build and run the program.

Usage

This program searches for Diagraph IJ printers on the network, connects to the first one found, and performs the following actions:

• Retrieves device information including version, status, errors, device info, and configuration.
• Lists files stored on the printer, such as label files.

Code Explanation

• The program uses the IJAPI.IJAPI class from the Diagraph-IJAPI library to interact with Diagraph IJ Printer.

• It searches for available IJ printers on the network using the Search method and connects to the first printer found.

• The program then retrieves device information, such as version, status, errors, device info, and configuration settings, and displays them.

• It lists the label files stored on the printer.

public class Program

    private static readonly IJ _api = new();

    public static async Task Main(string[] args)
    {
        //Search IJ printers on the network
        var foundIJPrinters = await _api.Search();

        foreach (var printer in foundIJPrinters)
        {
            //connect to printer
            var ij = _api.Connect(printer);

            if (ij.IsConnected)
            {
                Console.WriteLine($@"labels of {ij.Model} printer: {ij.IP} {new string('-', 70)}");

                foreach (var labelName in ij.Labels) Console.WriteLine($"Label: {labelName}");

                //Read device configuration
                Console.WriteLine(new string('-', 40));
                foreach (var configKey in ij.RequestConfigurationKeys())
                    Console.WriteLine($"configKey: {configKey} value: {ij.RequestConfigurationString(configKey)}");

                //Read device infos
                Console.WriteLine(new string('-', 40));
                foreach (var deviceInfokey in ij.RequestDeviceConfigurationKeys())
                    Console.WriteLine(
                        $"deviceInfokey: {deviceInfokey} value: {ij.RequestDeviceConfigurationString(deviceInfokey)}");

                do
                {
                    //Read current status
                    Console.WriteLine($"Status: {ij.Status}");
                    Console.WriteLine($"LabelName: {ij.LabelName}");
                    Console.WriteLine($"PrintCount: {ij.PrintCount}");
                    Console.WriteLine($"EncoderSpeed: {ij.EncoderSpeed}");
                    Console.WriteLine($"ProductDetected: {ij.ProductDetected}");

                    Console.WriteLine();
                    Console.WriteLine("Press enter to continue, Escape to Quit");
                    Console.WriteLine();
                } while (Console.ReadKey(true).Key != ConsoleKey.Escape);
            }
            else
            {
                Console.WriteLine("Not connected: " + ij.IP);
            } 
        }

        Console.WriteLine();
        Console.WriteLine("Press enter to continue");
        Console.ReadLine();
    }
}

Download and upload a label

var labelName = "label.next" // "label.prd"
var desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
var labelFile = Path.Combine(desktopPath, labelName);

//download a label
var labelContent = ij.GetLabel(labelName, true); //embedding the referenced bitmaps
File.WriteAllText(labelFile, labelContent);

//upload a label. The embedded bitmaps are restored 
ij.UploadLabel(labelFile);
