Description

Defines the height of the bars (in dots) for barcodes. The height is defined in n/203 inch increments. For example, specify 203 as the value for n to print a 1-inch high barcode. The barcode height is always rounded up to the next multiple of 8.

Parameters

GS k Print Barcode

Description

Prints a barcode at the current position in the current orientation. The n parameter selects the symbology to be printed. (See the table below.) The m parameter specifies how many characters are to be encoded as part of the barcode. If the number of characters to be encoded is variable, the m parameters can be set to zero. This will cause the printer to read the next character sent as a delimiter character. Further characters will then be encoded into the barcode until a character is found that matches the start character.
