Q. What does it do?

A. Just Barcodes CL allows you to generate bitmap images of barcodes. These may be saved or copied for use with other software and application programs.

Q. Can I design labels with it?

A. Not directly. Just Barcodes CL does not have a graphical user interface (GUI). It is designed to generate barcodes for use by other programs.

Q. How do I obtain a barcode number for my product?

A. Before you can use UPC or EAN codes in retail applications, you need to get an EAN.UCC company prefix, by contacting your GS1 Member Organisation. Please view the following web page for more information: http://www.ean-int.org/productssolutions/barcodes/implementation/

At the time of writing, the above page includes a link showing where to contact the appropriate authority for your part of the world. Once you have a company prefix, you can form a barcode number by appending your own item reference number to it. Then you can generate the barcode using a program such as Just Barcodes CL, ready for printing on your product.

Alternatively, go to the GS1 home page at: http://www.ean-int.org

Q. Where can I find out more about ISBN numbers for Bookland EAN?

A. The ISBN Users' Manual, available at www.isbn-international.org/en/manual.html is a good place to start.

Q. Why is there no graphical user interface (GUI) ?

A. Just Barcodes CL is designed to be used within automated systems - the CL in the name stands for Command Line. For this reason, it does not have a graphical user interface. (A couple of options do actually display a window. However, these are not used during normal operation.)
For a version with a graphical user interface, please look at our other barcode product instead: Just Barcodes. Its home page is at: http://www.neonsinesoftware.co.uk/justbarcodes

Q. Why was Just Barcodes CL renamed?

A. Before 17 April 2011, Just Barcodes CL was called Just Bar Codes CL. It was renamed because we think that more people search for "barcode" than for "bar code", so it should make it easier to find. We started with "bar code" because we originally thought that being technically correct was the most important thing. We did not rename the executable (jbccl.exe) to help with backwards compatibility. The default installation path is different though.


User Questions

Q. I cannot get the exact magnification % value that I want.

A. The resolution you are using determines what magnification values are possible.

Q. Why do I get black horizontal lines across my TIFF files?

A. Just Barcodes CL saves the TIFF files correctly, but some software fails to render certain compressed TIFF files correctly, including the previews in Vista and Windows 7. For Windows 7, this hotfix is available from Microsoft. More information is on this Microsoft web page. An alternative is to save the files without compression (this is set using Preferences).

Q. Where can I get the OCR-B font recommended for EAN-8, EAN-13, UPC-A or UPC-E barcodes?

A. One source is www.myfonts.com. The suggested type is TrueType for Windows. We do not supply this font in order to keep the price to a minimum. (Some users may already have this font on their system. Others may use a symbology that does not require OCR-B, such as Code 39 or Code 128.)
