Barcode Field Instructions

Table 1 shows the barcode field commands. The number in brackets denotes the print ratio. Each command produces a unique barcode.

As another reference to the barcode field commands ratio, see Table 1.

Additionally, each barcode field command can be issued with a definition parameter string. The parameter string defines field rotation, height, and interpretation line status for all barcodes. For some barcodes, the parameter string also sets a check digit, start character, and/or stop character. Use the definition parameter string to command the printer to print barcodes of appropriate heights and densities that conform to the specifications of the application.

The use of the parameter string is optional because all parameters have default values. If the default values for all of the barcode parameters suit the application, then only the barcode command needs to be entered.

Parameters in barcode field commands are “position specific.” If a value (other than the default value) is manually entered for one parameter the ZPL II delimiter character (a comma) must be used to mark the position of the preceding parameters in the string.

To change just the third parameter, enter two commas and then the value for the third parameter. The default values will be automatically used for the first and second parameters.
