Barcodes

Section 8

This section describes how to use your printer to generate barcodes.

Barcode Function

You can print barcodes on your printer in both IBM and Epson emulation modes.

In the 248x printer’s Data Options setup menu, the barcode option must be set to ENABLE to reserve 1K of the receive buffer for barcode processing. If the option is not set to ENABLE, barcode printing is not possible. For 249x printers, buffer space is reserved automatically for barcode processing.

Resident barcodes include:

EAN-13UPC-A

EAN-8POSTNET

Code 39

Code 128

Interleaved 2of5

A barcode is a set of adjacent parallel bars and spaces of specific widths that has an encoded algorithm for the barcode type.

The module width is the base unit of measurement used to determine the overall width of a printed barcode. A character width within a barcode is an integral multiple of a module width. Each bar and space is an integral multiple of a module width. In order to account for differences in tolerances and optical conditions between printing and scanning a barcode, your printer provides "space width adjustment" for fine adjustment of space and bar ratios.

Barcodes may be printed with or without human readable characters. Typically, these characters are printed below the barcode, which allows the data to be manually entered if the barcode cannot be scanned.
