a bit of source: VB.net

oPdf.SetValue("Output", tcDoelFileName)
'------------------------------------------
oPdf.SetValue("ConfirmOverwrite", "no")
oPdf.SetValue("Format", "PDF")
oPdf.SetValue("RememberLastFileName", "no")
oPdf.SetValue("RememberLastFolderName", "no")
oPdf.SetValue("ShowSaveAs", "never")
oPdf.SetValue("Showsettings", "never")
oPdf.SetValue("ShowProgress", "no")
oPdf.SetValue("ShowProgress", "no")
oPdf.SetValue("ShowProgressFinished", "no")
oPdf.SetValue("SuppressErrors", "Yes")

Try
'----------------
pd.PrintController = New StandardPrintController
'----------------
Dim lEncod As System.Text.Encoding
lEncod = System.Text.Encoding.Default
streamToPrint = New StreamReader(tcFileToConvert, lEncod)
printFont = New Font("Courier New", 10) 'MONOSpace font!
'--------------------
pd.DefaultPageSettings.Margins.Left = 5
pd.DefaultPageSettings.Margins.Right = 5
pd.DefaultPageSettings.Margins.Top = 5
pd.DefaultPageSettings.Margins.Bottom = 5
'----------------------------------
AddHandler pd.PrintPage, AddressOf Me.pd_PrintPage
pd.Print()
RemoveHandler pd.PrintPage, AddressOf Me.pd_PrintPage
Catch ex As Exception
Me.SetErrorInfo(ErrorCodes.CreateDocument, ex)
iRetValue = -1
Finally
streamToPrint.Close()
End Try
