AUTOMATIC TICKET DELIVER RRS feed

  • Question

  • Good evening
    I write a vb code that allows to make an automatic printing on a printer "epson" without a dialog box or button "print".
    now what I want the printer to do is this:
    When printing a ticket, it waits for the user to remove the ticket before it prints another one. the first ticket not removed blocks the arrival of the second ticket.
    here is my code:

     Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
            Me.Activate()
            
        End Sub
     Private Sub Form1_Activated(ByVal sender As Object,
    ByVal e As System.EventArgs) Handles MyBase.Activated
           
                   PrintDocument1.PrinterSettings.PrinterName ="epson" 
            If PrintDocument1.PrinterSettings.IsValid Then
                PrintDocument1.Print()

            Else
                MessageBox.Show("invalid.")
                'End If
            End If
        End Sub

    Private Sub PrintDocument1_PrintPage(sender As Object, e As Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
            e.Graphics.DrawString(vbNewLine + vbNewLine + "NUMERO" + " " + ComboBox1.Text + "  ", New Font("Elephant", 20, FontStyle.Bold), Brushes.Black, 10, 15)

        End Sub

  • You will need to find the escape codes for the specific printer e.g. this page.

    You can send control commands directly to a printer using the code described here:
