Try this method "prt" by passing the "Text" and "PrinterName", if the printer is a network printer then specify the full network path. eg. "\\sharedlocation\printername"

C#

Public Class PrintHelper
    Friend TextToBePrinted As String

    Public Sub prt(ByVal text As String, ByVal printer As String)
        TextToBePrinted = text
        Dim prn As New Printing.PrintDocument
        Using (prn)
            prn.PrinterSettings.PrinterName = printer
            AddHandler prn.PrintPage, _
               AddressOf Me.PrintPageHandler
            prn.Print()
            RemoveHandler prn.PrintPage, _
               AddressOf Me.PrintPageHandler
        End Using
    End Sub

    Private Sub PrintPageHandler(ByVal sender As Object, _
       ByVal args As Printing.PrintPageEventArgs)
        Dim myFont As New Font("Courier New", 9)
        args.Graphics.DrawString(TextToBePrinted, _
           New Font(myFont, FontStyle.Regular), _
           Brushes.Black, 50, 50)
    End Sub
End Class

hope this will help...
