C # Enumerate all printers installed by the system

Print recently in the forum many netizens asked "How to install all the printers in Windows listed", in the following program we will be installed in the system of the printer listed in the list box, while the default printer set the default value.

In the following program we used two main classes, all of the printer list out of the PrinterSettings class, get the system default printer used PrintDocument class, let's do a hands-on.

To create a new Windows Form project, and then join a lable and a combox, it's OK, the key is below, how we get the default printer, we have to use the following statement.

PrintDocument Prtdoc = new PrintDocument ();
String strdefaultprinter = Prtdoc. printersettings.printername;//get the default printer name

With the default printer, we'll list all the printers.

PrinterSettings class has a InstalledPrinters property, do not know what it is to do, check MSDN as explained below:
Printersettings.installedprinters gets the names of all the printers installed on the computer.

The following definitions are defined in C #:

[C #]
[Serializable]
[ComVisible (False)]
public static Printersettings.stringcollection InstalledPrinters
{get;}

Property value

Printersettings.stringcollection, which represents the names of all printers installed on the computer.

Abnormal

Exception type condition
Win32Exception failed to enumerate available printers

Note

You can use a collection of installed printer names to provide the user with a choice of printer to print to.

The following example populates the Comboinstalledprinters combo box with an installed printer, and also uses the PrinterName property to set the printer for printing when the change is selected. The PopulateInstalledPrintersCombo routine is invoked when the form is initialized. The example assumes that there is a PrintDocument variable named Printdoc, and that a specific combo box exists.

[C #]
The following brackets are added to their own translations
private void PopulateInstalledPrintersCombo ()
{
ADD list of installed printers found to the combo box. (Add all the machines in the system to the list box)
The pkinstalledprinters string is used to provide the display string. (The string displayed in the list box is provided by Pkinstalledprinters)
foreach (String pkinstalledprinters in
Printersettings.installedprinters)
{
COMBOINSTALLEDPRINTERS.ITEMS.ADD (pkinstalledprinters);
}
}

private void Comboinstalledprinters_selectionchanged (object sender, System.EventArgs e)
{

Set the printer to a printer in the combo box when the selection changes. (Set the selected printer when the list box changes)

if (Comboinstalledprinters.selectedindex!=-1)
{
The combo box ' s Text property returns the selected item ' s text and which is the printer name. (Displays the selected printer name in the list box)
Printdoc.printersettings.printername= Comboinstalledprinters.text;
}

}

Read the MSDN instructions, understand a lot of it, here is the complete code I write practice.
