Print receipt in vb.net

receipt

I am trying to print the above receipt using vb.net. However, as seen in the image, the amount figure appears on a new line. What am I doing wrong?

Below is the code I use:

Private Sub PrintDocument1_PrintPage(sender As Object, e As PrintPageEventArgs) Handles PrintDocument1.PrintPage

        Dim offset As Integer = 15
    Dim itemdesc As String = "Item".PadRight(30)
        Dim Pricedesc As String = "Price".PadRight(8)
        Dim qtydesc As String = "Qty".PadRight(5)
        Dim amtdesc As String = "Amount"
        Dim descline As String = itemdesc + Pricedesc + qtydesc + amtdesc
        e.Graphics.DrawString(descline, New Font("Courier New", 8, FontStyle.Regular), Brushes.Black, 25, 100 + offset)
        offset += 10
    Dim startx As Integer = 25
        Dim starty As Integer = 100

        Dim font As New Font("Courier New", 8, FontStyle.Regular)
        Dim item As String
        Dim price As String
        Dim qty As String
        Dim amount As String

    Dim productline As String
        For k As Integer = 0 To dgvSales.RowCount - 2

            item = dgvSales.Rows(k).Cells(1).Value.ToString.PadRight(30)
            price = dgvSales.Rows(k).Cells(3).Value.ToString.PadRight(8)
            qty = dgvSales.Rows(k).Cells(4).Value.ToString.PadRight(5)
            amount = dgvSales.Rows(k).Cells(5).Value.ToString
            productline = item + price + qty + amount
            e.Graphics.DrawString(productline, font, Brushes.Black, startx, starty + offset)
            offset += 20

        Next
End Sub

There are three possibilities:

  • Your column qty (column idx 4) contains a string that has a newline in it. If this is the case, you can just Trim() the value before joining the values.
  • Your column amount contains many spaces, or begins with a newline character. If this is the case, you can also fix it by using Trim(), this time on the variable amount before joining the values.
  • It's something else that I haven't thought of yet :).
