            Dim CrTables As Tables
            Dim CrTable As Table
            Dim cryRpt As New ReportDocument
            cryRpt.Load(Application.StartupPath + "\" + "tic.rpt")

            With crConnectionInfo
                .ServerName = "localhost"
                .DatabaseName = "opd"
                .UserID = "root"
                .Password = ""
                .IntegratedSecurity = False
            End With

            CrTables = cryRpt.Database.Tables
            For Each CrTable In CrTables
                crtableLogoninfo = CrTable.LogOnInfo
                crtableLogoninfo.ConnectionInfo = crConnectionInfo
                CrTable.ApplyLogOnInfo(crtableLogoninfo)
            Next

            cryRpt.SetDatabaseLogon("root", crConnectionInfo.Password, crConnectionInfo.ServerName, crConnectionInfo.DatabaseName, crConnectionInfo.IntegratedSecurity)

            cryRpt.Refresh()
            ''add parameters 
            cryRpt.SetParameterValue(0, txtOPD.Text)
            cryRpt.PrintOptions.PrinterName = "EPSON L360 Series" ''specify the printer name here, if none is specified, the default printer will bee used.
            cryRpt.PrintToPrinter(1, False, 0, 0)
        Catch ex As Exception

        End Try
    End Sub

 Private Sub cmdSave_Click(sender As Object, e As EventArgs) Handles cmdSave.Click

Issue seems with PrinterName, Give the proper network path of PrinterName or Write the following code to get your default printer:

cryRpt.PrintOptions.PrinterName = GetDefaultPrinter()

Private Function GetDefaultPrinter() As String
    Dim settings As PrinterSettings = New PrinterSettings()
    For Each printer As String In PrinterSettings.InstalledPrinters
        settings.PrinterName = printer
        If settings.IsDefaultPrinter Then
            Return printer
        End If
    Next
    Return String.Empty
End Function
