Chapter 6 - Designing Bar Code Labels Choosing the Human-Readable Font With BARFONT Specifies the single-byte font to be used for the human-readable interpretation. In some bar codes, such as EAN/UPC, the interpretation is an integrated part of the code. The font can be specified in regard to: • Default font (Swiss 721 BT). • Size in points. Default is 12. • Slant in degrees. Default is 0. • Vertical offset. Specifies the distance in dots between the bottom of the bar pattern and the top of the interpretation characters. Default is 6. • Height magnification. Default is 1. • Width magnification. Default is 1. • Width enlargement in percent. Default is 100. To disable bar code interpretation printing, use BARFONT OFF. Specifying Input Data With PRBAR Depending on the type of bar code, input data for the bar code can be entered in the form of numeric and/or string expressions. String constants must be enclosed by quotation marks. Variables are useful for printing the time, date, or various counters, or for when the same information is to appear in several places, such as in plain text and as bar code input data. Summary for Bar Code Fields To print a bar code field, the following information and instructions must be specified. If no value is given, defaults are substituted.
