I cannot seem to find barcode 39 fonts to use in mac

You can get a legal free copy of the barcode 39 font here. Make sure to read the heading, Using the Code 39 Barcode Font. You can also get it here.

For the first link above, they give you two choices to download the font. DO NOT use the recommended link. Unless you like adware along with everything you may download from a garbage site like download.com. The other link downloads the font directly. It also comes with a lot of junk. Throw away the INSTALL.exe file. Most of the rest of it in the subfolder are samples. The only thing of actual importance is the .ttf font. Or, use the newer .otf (OpenType) font.

The font makes the barcode itself. If you want the numbers to appear under it, you have to do that separately. Such as with the standard MICR font. Or you could use a simple to read font such as Courier (Courier in particular because it's a monospaced font).

I tested both of these fonts further, and in my first sentence above, I would not recommend the second link. It contains two fonts that conflict with each other, and aren't even the same. The first link (to IDAutomation.com) is a much more complete barcode 39 font that has numbers and letters under each character, so as you type it in, both the bar code and its human readable number are produced at the same time.

You're welcome. Glad you found a solution. 🙂
