Hi, getting weir problem with printing directly to printer port with API. It seems like it prints one copy and then if press to print again it will not print.. .. checked spooler and there is nothing in spooler. Click a couple of times and it will print out but with previous data. Does anyone have this problem b4?
Can you give us a code snippet to look at?
I am using http://support.microsoft.com/?scid=kb;EN-US;322090
RawprinterHelper Class from above.
==========================================
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim t As String
t = "This is a test"
Dim pd As New PrintDialog
pd.PrinterSettings = New PrinterSettings
If (pd.ShowDialog() = DialogResult.OK) Then
RawPrinterHelper.SendStringToPrinter(pd.PrinterSettings.PrinterName, t)
End If
End Sub
Difficult to say as they didn't put any error handling in their code.
I will rewrite it and post it here tomorrow.
I am developing a POS app, and requires to print to Receipt printers. I did so digging, and it seems like there are many ways to have it print to this kind of printer. 1. with API & windows driver installed *which is what I am working on*, 2. using company DLLS (I am using STAR receipt printer, and they have a dll included for use in VB apps. Tried, same thing happens) 3. OLE printer drivers for direct access without installing windows driver. * This I haven't tried.
Did you ever get an answer to this? I am experiencing the same thing.

Sorry to hear that. Thanks for getting back to me though.
I think what I am going to try next is to write a dll using VB6 to print and call it from the main app I'm writing.
Thanks again.
