The problem seen to appear again in printing job...
I have a printer(Epson TM-T88IV Receipt). Before printing, i would like to check if printer is available for printing or not (connect or not). if not, i will show the print preview form. otherwise it will print automatically
any solution in vb.net code
Thanks in advance

I'm not 100% sure this will work so try it first:
'usage
For Each prn As String In PrinterSettings.InstalledPrinters
Debug.WriteLine(String.Format("Is printer {0} online? {1}", prn, CheckPrinter(prn).ToString))
Next
'function to test printer status
Private Function CheckPrinter(ByVal printerName As String) As Boolean
Try
Dim printDocument As PrintDocument = New PrintDocument
printDocument.PrinterSettings.PrinterName = printerName
Return printDocument.PrinterSettings.IsValid
Catch ex As System.Exception
Return False
End Try
End Function

As you use Vb.net I guess you are on a windows machine. Use your operating systems API. Like e.g. GetPrinterStatus.
