The following conditions are required for barcode printing:

❏Barcode printing is always performed unidirectionally. However, when it is mixed with raster bit image data, neither barcode nor raster bit image data is printed.

❏A barcode is not printed when part of the barcode extends beyond the right margin.

❏When barcode data and text data are mixed in a data sequence, barcodes and text are printed in the same place.

❏The start and stop (*) characters of Code 39 are added to human readable characters.

❏The initial data of Code 128 (Set A, B, or C) is identified as the first data of Code 128, and must be hexadecimal (41, 42, and 43, respectively).

❏When Code 128 Set C and Interleaved 2 of 5 are selected, barcode data requires an even number data string. However, if an odd number string is sent, a 0 is automatically added, making it an even number data string.

❏The barcode print start position (except for POSTNET) is always 40/360 inch above the baseline.
