TppLabel with color setting doesn't print out in Epson LQ100 printer on Windows 10

ccy

I have a TppLabel control:

    object ppLabel1: TppLabel
      DesignLayer = ppDesignLayer1
      UserName = 'Label1'
      Border.mmPadding = 0
      Caption = 'Label1'
      Font.Charset = DEFAULT_CHARSET
      Font.Color = clBlue
      Font.Name = 'Arial'
      Font.Size = 10
      Font.Style = []
      FormFieldSettings.FormSubmitInfo.SubmitMethod = fstPost
      FormFieldSettings.FormFieldType = fftNone
      Transparent = True
      mmHeight = 4234
      mmLeft = 10583
      mmTop = 6879
      mmWidth = 10055
      BandType = 0
      LayerName = Foreground
    end

Preview the report is fine, the control show blue color text. When I try to print it on Dot Matrix non color printer (Epson LQ100). The control does not print out.

If I change the font color to clBlack. The control does print out.

This happen when I upgrade to ReportBuilder 20 build 255.

The problem didn't happen in last few releases of ReportBuilder.
