Hello friends
My name is Sarfaraz. I am developing a software for a client who needs to print receipts on a Dot Matrix printer.
I know how to print values of Text box but that is not the best way to print on Dotmatrix printer.
Please help me in the following:
1. Should i load the details of text boxes and listbox to a grid and then print on a receipt. or
2. Should I save the contents of text boxes and listbox to text file and print. or
3. Sould I use crystal reports for the recipt to print.
Please help me in that.
Thank you

Why not printing on it as on any other printer installed in the system?
When you say "text box", the question is: which one? Full type name, please.

Solution 1

For Dot Matric printer, #2 is the best option. Crystal reports and other graphics format will be really slow and will use lot of ink.

Save to a text file and execute the shell command

type "filename.txt" > prn

Dear Akbar Bhai
Please elaborate I am new to VB.net actually i am able to write the values to a text file like


 Private Sub btnnew_Click(sender As Object, e As EventArgs) Handles btnnew.Click
        Try
            Dim file_name As String = Application.StartupPath() & "/text.dat"
            Dim stream_writer As New IO.StreamWriter(file_name, False)
            Try
                stream_writer.WriteLine(txtname.Text)
                stream_writer.WriteLine(txtopd.Text)
            Finally
                stream_writer.Close()
            End Try
        Catch exc As Exception
            ' Report all errors.
            MsgBox(exc.Message, MsgBoxStyle.Exclamation, "Read " & "Error")
        End Try

But I need an example for help for printing like you mentioned type "filename.txt" > prn
Thank you

After creating the file, you can send that file to Printer using Shell command. Refer code below...


Dim file_name As String = Application.StartupPath() & "/text.dat"
Dim command as String = "type " + file_name + " > prn"
Dim proc As Process = New System.Diagnostics.Process()
proc.StartInfo = New System.Diagnostics.ProcessStartInfo("cmd", "/c " & command)
proc.StartInfo.RedirectStandardOutput = True
proc.StartInfo.RedirectStandardError = True
proc.StartInfo.UseShellExecute = False
proc.StartInfo.CreateNoWindow = True
proc.EnableRaisingEvents = False
proc.Start()
proc.WaitForExit()
