C# Network Printing

Question

I am able to get the list of network printers via this code:

private void Form1_Load(object sender, EventArgs e)
{
  foreach (String printer in PrinterSettings.InstalledPrinters)
  {
    listBox1.Items.Add(printer.ToString());
  }
}

For each network printer, I want to extract out more information like: (a) get document information, like number of pages printed, filename, file-size, etc.

(b) get computer IP address from which document was printed.

(c) get username of who printed the document.

How do I achieve the above? any code samples would be appreciated. Do I have to look into Windows Management Instrumentation(WMI) stuffs?

Answer 1

You might be able to get out some of the information via WMI:

If you want more information, and your printers support it, you might be able to use SNMP, here's an article\library that might help you find out how to use that:

Answer 2

yes, I am able to get all the properties and values from WMI, of Win32_Printer using below code, but I could not retrieve basic information like (a) get document information, like number of pages printed, filename, file-size, etc. (b) get computer IP address from which document was printed. (c) get username of who printed the document.

Code:

private void button1_Click(object sender, EventArgs e) { string printerName = "Ricoh-L4-1"; string query = string.Format("SELECT * from Win32_Printer WHERE Name LIKE '%{0}'", printerName); ManagementObjectSearcher searcher = new ManagementObjectSearcher(query); ManagementObjectCollection coll = searcher.Get();

        foreach (ManagementObject printer in coll)
        {
            foreach (PropertyData property in printer.Properties)
            {
                listBox1.Items.Add(string.Format("{0}: {1}", property.Name, property.Value));
            }
        } 

    }
