Bar Codes

EAN8

A fixed-length data string of 7 ASCII characters may be printed using the EAN

8 bar code. The string length must be 7 and may use any of the standard

characters 0 through 9. If a non-valid character or string length is used, a

blank non-readable bar code will be printed; non-valid characters are not

substituted or deleted. The width of the printed bar code is not variable and is

1.25 inches.

EAN13

A fixed-length data string of 12 ASCII characters may be printed using the

EAN 13 bar code. The string length must be 12 and may use any of the

standard characters 0 through 9. If a non-valid character or string length is

used, a blank non-readable bar code will be printed; non-valid characters are

not substituted or deleted. The width of the printed bar code is not variable

and is 1.56 inches.

Royal Mail

A variable length data string may be printed using the “Royal Mail 4 State

Customer Code”. The string may use any character from 0 through 9 and

alpha characters A through Z. A complete bar code consists of a set of distinct

bars and spaces for each character followed by a checksum character and

enclosed by a unique start bar, stop bar and quiet zone. A second version of

the Royal Mail barcode prints with no stop bar, start bar or checksum

character.

UCC/EAN 128

The UCC/EAN-128 bar code contains special characters which use unique

codes to identify the leading and trailing end of the bar code. EAN/UCC 128

supports a full ASCII character set and provides standard alphanumeric

keyboard characters and control and special characters.

The UCC/EAN-128 data structure requires an Application Identifier (AI) at the

beginning of barcode data. Each AI determines the format and length of the

data which follows. Refer to Table 12 for more detail.
