How to Print Crystal Reports with parameters

Hello,

 I have two options for my report, sending it to the viewer or sending it directly to the printer.  I have managed to get the parameters passed when using the viewer, but it just wont work when going directly to print.

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared

Private mReport As ReportDocument

mReport = New ReportDocument()
mReport.Load("MYreportName and PathHere.rpt")
dim  strDB = "tableNameHere"

dim WONum as string = "123ABC"

If printFlg = "YES" Then   'printFlg set and defined somewhere else
mReport.SetParameterValue("WONum", WONum)

mReport.PrintOptions.PrinterName = "PrinterName"
mReport.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.DefaultPaperSize
mReport.PrintToPrinter(1, False, 0, 0)

Else
'** Parameter Settings ***'
Dim paramFields As New CrystalDecisions.Shared.ParameterFields()
Dim paramField As New CrystalDecisions.Shared.ParameterField()
Dim paramRange As New CrystalDecisions.Shared.ParameterDiscreteValue()

paramField.ParameterFieldName = "WONum" ' Parameter Name In Crystal Report
paramRange.Value = WONum  ' value For Parameter Field
paramField.CurrentValues.Add(paramRange)
paramFields.Add(paramField) ' To add parameter in parameterslist

CR1.ParameterFieldInfo = paramFields 'to pass parameter inf.to CRV
'*** Parm Settings End ***'

CR1.ReportSource = mReport
End If

sorry, wasnt sure how to add the code.  Anyway, when it goes to directly to printer after I have published the solution, it says missing parameter value, but if I run it on the development computer it works fine.  Do I have syntax errors or am I missing a library?  

I get the following warnings when I publish but dont know if they are the issue or if I can just ignore them.  Any feedback will be just awesome!!

thanks!
