These problems are experienced because all Code 128 and Interleaved 2 of 5 fonts use extended ASCII characters that do not work the same on all operating systems, applications and language settings other than ISO Latin 1. The main problem with the Macintosh computer is that it uses the MAC Roman character set and Windows PCs uses ISO Latin 1. The problem does not seem to occur as much on Macintosh OS-X machines as it does with others.

Provided that the barcode is formatted properly to the font with IDAutomation’s Font Tools, the problem is occurring if empty boxes are visible in the barcode.

Empty boxes appear in the barcode

This problem is resolved by using IDAutomation’s Universal Barcode Font Advantage™, which supports linear barcodes as a single font on multiple operating systems, languages and locales.

Additional Solutions:
  • If this problem is experienced with US Western and ISO Latin 1 regional settings, the problem is most likely one of the following:
    • The data is incorrect for the font chosen, for example, a Code 128 function was used with an Interleaved 2 of 5 font.
    • The data is not formatted for the font correctly. To solve this, compare the function logic with IDAutomation’s VBA code.
    • A custom function created for IDAutomation fonts is not working properly. To solve this, compare the function logic with the VBA code.
  • An alternative is to use one of the barcode components such as IDAutomation’s Java Barcode Components which is compatible with any operating system including the Macintosh.

If this problem is experienced on the MAC, there are a few other options that may solve this problem:

  1. Use IDAutomation’s Code 128 or Interleaved 2 of 5 Font with FileMaker and the FileMaker Barcode Plug-in. This plug-in prints from the upper ASCII characters from ASCII 133-145 from the MAC Roman character set (see the chart below) and works cross-platform between PC’s and MAC’s in this way.
  2. Program the application to print extended characters from alternate character locations as shown in the chart below.
