monitoring print job

In this example, we subscribe to the JobAdded event of each print queue to log information about print jobs as they are added to the queue. You can also subscribe to other print job events like JobCompleted, JobPrinted, etc., to capture additional information as needed.

using System;
using System.IO;
using System.Printing;

public class PrinterMonitor
{
    public static void Main(string[] args)
    {
        LocalPrintServer printServer = new LocalPrintServer();

        foreach (PrintQueue printQueue in printServer.GetPrintQueues())
        {
            printQueue.JobAdded += PrintQueue_JobAdded;
            // Add other event handlers for print job events, if needed
        }

        Console.WriteLine("Monitoring print queues. Press Enter to exit.");
        Console.ReadLine();
    }

    private static void PrintQueue_JobAdded(object sender, PrintJobInfoEventArgs e)
    {
        PrintQueue printQueue = (PrintQueue)sender;
        PrintSystemJobInfo job = e.PrintJobInfo;

        // Log the print job information to a file
        string logMessage = $"Print Job ID: {job.JobIdentifier}, User: {job.Submitter}, Page Count: {job.NumberOfPagesPrinted}";
        LogToFile("print_job_log.txt", logMessage);
    }

    private static void LogToFile(string fileName, string message)
    {
        using (StreamWriter writer = File.AppendText(fileName))
        {
            writer.WriteLine($"{DateTime.Now:yyyy-MM-dd HH:mm:ss}: {message}");
        }
    }
}
