How to get Printer Submitted Jobs in C# ?

Here is a handy method that gives you a collection of all the jobs submitted to the printer. This method uses the ManagementObjectSearcher and the ManagementObjectCollection classes from the .NET framework. The query “SELECT * FROM Win32_PrintJob” is used to get a collection of the submitted jobs. These jobs are added to a StringCollection and this collection is returned back.

#region GetPrintJobsCollection

        /// <summary>
        /// Returns the jobs in printer queue
        /// </summary>
        /// <param name="printerName">Printer Name.</param>
        /// <returns>StringCollection</returns>
        public StringCollection GetPrintJobsCollection(string printerName)
        {
            StringCollection printJobCollection = new StringCollection();
            try
            {
                //Query the printer to get the files waiting to print.
                string searchQuery = "SELECT * FROM Win32_PrintJob";

                ManagementObjectSearcher searchPrintJobs = new ManagementObjectSearcher(searchQuery);
                ManagementObjectCollection prntJobCollection = searchPrintJobs.Get();


                foreach (ManagementObject prntJob in prntJobCollection)
                {
                    String jobName = prntJob.Properties["Name"].Value.ToString();

                    //Job name would be of the format [Printer name], [Job ID]
                    char[] splitArr = new char[1];
                    splitArr[0] = Convert.ToChar(",");
                    string prnName = jobName.Split(splitArr)[0];
                    string documentName = prntJob.Properties["Document"].Value.ToString();
                    if (String.Compare(prnName, printerName, true) == 0)
                    {
                        printJobCollection.Add(documentName);
                    }
                }
            }
            catch (Exception ex)
            {
                // Log the exception.
            }
            return printJobCollection;
        }
