This class is located in System.Drawing.Printing namespace.
so you need to add a reference System. Drawing and then importing it using a statement.
using System.Drawing.Printing;
To get all the printers available, you need to iterate the string values through PrinterSettings.
For example
Add a ListBox to your Windows application and then use the foreach statement for an iteration.
foreach (string printName in PrinterSettings.InstalledPrinters)
{
listBox1.Items.Add(printName);
}
This will show you all the available Printers installed on your computer as seen below.
Because I've not installed any physical printers on my computer it shows the printer services.
