From Elfring Fonts Inc.:
Print your own bar code 2/5 interleaved or ITF-14 from within any Windows program! This scalable TrueType and PostScript font set lets virtually any existing Windows program print bar codes. Bar code 2/5 interleaved is a high density numeric bar code, does not require a checksum, and lets you encode numbers only (you must have an even number of digits.
This bar code package contains 20 fonts. These fonts include both a standard (bar codes only) and a human readable (bar codes with text or numbers below) versions of bar code 2/5 interleaved. The bar codes also come with and without bearer bars. Each of these bar code types comes in five different aspect ratios, so you can vary the height and width of the bars independent of each other. This lets you print bar codes with the same height, but with different bar thicknesses.
Our software lets you print your own barcodes on your documents and packaging, or you can print sheets of labels with bar code 2/5 using our Bar25i utility. This program can even export your bar code as a gif, jpg, or png. Want to print barcodes in Access or Excel? We include Visual Basic macro functions that do all the work for you. If you don't understand bar codes, just run the Bar39 utility program (included in this package) to build barcodes for you. The download version includes a manual in Rich Text format compatible with any Windows word processor. The physical package comes on CD with a printed manual.
