The EAN-8 bar code data field must only contain numeric data, and must be eight
bytes long, check digit included. The EAN-8 character repertoire provides 0 to 9
ASCII numeric figures. n indicates the bar code height in units of 1/6 inch and
must be in the range 1 to 12. p must be NUL (hex. 00) if no Human Readable
Characters are to be printed, and 1 (hex. 01) if they are to be printed. The range of
values for n and p parameters can be increased of 32 dec.

The EAN-13 bar code data field must only contain numeric data, and must be 13
bytes long, check digit included. The EAN-13 character repertoire provides 0 to 9

must be in the range 1 to 12. If you want to print the Human Readable

(hex. 00). The range of values for n and p parameters can be increased of 32 dec.
UPC-A DC4 DC4 ESC! n 3 p EM
The UPC-A bar code data field allows 10 numeric characters plus one system
number digit and one check digit, at the leftmost and rightmost positions
respectively. The UPC-A character repertoire provides 0 to 9 ASCII numeric
figures. n indicates the bar code height in units of 1/6 inch and must be in the
range 1 to 12. p must be NUL (hex. 00) if no Human Readable Characters are to
be printed, and 1 (hex. 01) if they are to be printed. The range of values for n and p
parameters can be increased of 32 dec.
