See the following paragraph for a step-by-step description on how to create a single valid barcode.
Step
1: Select the Barcode type
Select from the list the barcode type you want to create. See the manual for
a list of supported barcodes. Selecting a barcode type from the list will also
show some facts about this type at the bottom of the application's window.
Step 2: Enter the number or text you want to display as a barcode
In the example above the numbers "1234567" were entered. This data lies within the specifications of the selected type: Code EAN 8, seven digits plus checksum (which "BarcodeMaker" will calculate for you) so a valid barcode is generated and displayed. Also the converted string ("<BCDE=fgha>") is displayed. Going back to our example with MS Word this is the string you would have to enter to create a valid barcode. If the data you enter in "BarcodeMaker" does not lie within the specifications of the selected barcode type, the fields for "Converted String" and "Barcode" will remain empty.
Step 3: Getting the converted string into your application
In "BarcodeMaker" click "Copy String To Clipboard". In your application paste the string into your document (usually with Edit->Paste), select it and change the font to the barcode type you specified.
For
technical reasons one font can display more than one barcode type. Here's a
list of the fonts installed and the barcode types they can display:
