AUTOMATIC TICKET DELIVER

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.
