Remarks

The PrinterCollection class exposes a global Printers collection that returns a collection of available printers on the system.

The Printers collection uses a zero-based index: the first Printer has an Index of 0, the second has an Index of 1, and so on.

The Printers collection is read-only; you cannot add or remove a Printer object from Printers.

참고

Functions and objects in the Microsoft.VisualBasic.PowerPacks.Printing.Compatibility.VB6 namespace are provided for use by the tools for upgrading from Visual Basic 6.0 to Visual Basic 2010. In most cases, these functions and objects duplicate functionality that you can find in other namespaces in the .NET Framework. They are necessary only when the Visual Basic 6.0 code model differs significantly from the .NET Framework implementation.

Examples

The following example demonstrates how to return a list of printers. It assumes that you have a ListBox control named ListBox1.

Dim i As Integer
For i = 0 To Printers.Count - 1
    ListBox1.Items.Add(Printers(i).DeviceName)
Next

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
