Printing bar code to LOCL printer

Question

I have created a smartform to print a bar code using bar code BC_CD39.  I call the smartform function in an ABAP program and then display it in PDF form using function:
call function 'SSFCOMP_PDF_PREVIEW'
     EXPORTING
          i_otf                    = otfdata
     EXCEPTIONS
          convert_otf_to_pdf_error = 1
          cntl_error               = 2
          others                   = 3.
The bar code does show on the PDF, but it is just showing as repeating bars of the same size. Like this:  
And when I print to LOCL printer, it prints out the same.  Why is it not printing/displaying the true bar code?

Hi
Which printer are you using? To print the Barcodes you need a separate Barcode printer see the following
To Create a Bar code prefix:
1) Go to T-code - SPAD -> Full Administration -> Click on Device Type -> Double click the device for which you wish to create the print control -> Click on Print Control tab ->Click on change mode -> Click the plus sign to add a row or prefix say SBP99 (Prefix must start with SBP) -> save you changes , it will ask for request -> create request and save
2) Now when you go to SE73 if you enter SBP00 for you device it will add the newly created Prefix
Create a character format C1.Assign a barcode to the character format.Check the check box for the barcode.
The place where you are using the field value use like this
<C1> &itab-field& </C1>.
You will get the field value in the form of barcode.
Which barcode printer are you using ? Can you download this file and see.

It will give an idea about barcode commands.

Detailed information about SAP Barcodes
A barcode solution consists of the following:
- a barcode printer
- a barcode reader
- a mobile data collection application/program
A barcode label is a special symbology to represent human readable information such as a material number or batch number
in machine readable format.
There are different symbologies for different applications and different industries. Luckily, you need not worry to much about that as the logistics supply chain has mostly standardized on 3 of 9 and 128 barcode symbologies - which all barcode readers support and which SAP support natively in it's printing protocols.
You can print barcodes from SAP by modifying an existing output form.
Behind every output form is a print program that collects all the data and then pass it to the form. The form contains the layout as well as the font, line and paragraph formats. These forms are designed using SAPScript (a very easy but frustratingly simplistic form format language) or SmartForms that is more of a graphical form design tool.
Barcodes are nothing more than a font definition and is part of the style sheet associated with a particular SAPScript form. The most important aspect is to place a parameter in the line of the form that points to the data element that you want to represent as barcode on the form, i.e. material number. Next you need to set the font for that parameter value to one of the supported barcode symbologies.
