2 Barcode/OCR Fonts
Barcode/OCR Fonts
This manual provides descriptions for types of barcode, character code and samples of
font usage, etc. for models equipped with the Barcode/OCR font option. The content of
this manual assumes the reader has a basic understanding of barcodes and barcode
standards.
The barcode relies heavily on printer paper and on the performance of the Barcode
Reader. Please read thoroughly before using.
Types of Barcode/OCR Fonts
The internal code for the barcode fonts is coded in the barcode symbologies listed below.
In general, assign a barcode font and data that is going to be expressed based on the
ASCII character set. However, be aware that the internal code for fonts may at times be
encoded using code that is different from ASCII code.
UPC/EAN
UPC and EAN (JAN) are numeric barcodes. The barcode pattern is defined so that both
can be expressed as fonts even though they have different standards. They come in
standard and abbreviated formats and may be augmented with add-ons. The check digit
is modulus 10 with weight 3.
The check digit for a 5-digit add-on is modulus 10 (no check digit with a 2-digit add-
on). Use ASCII characters 0 to 9 for the font of the left odd parity. Use Hex 41 to 4A (A
to J) for the right even parity. Use Hex 61 to 6A (a to j) for the left even parity. Show all
numerals 0 to 9.
The gap used for the add-on is defined to Space: Hex 20. The guard bar, center bar, Stop
for abbreviated format, Start for add-on and delineator for the add-on are come in two
types: 1) the height is the same as numerals and 2) the bar is underneath the numerals
and extends out past the numeral. Each are defined in (: Hex28, - : Hex2D,) : Hex29, * :
Hex2A, + : Hex2B and X : Hex58,] : Hex5D, Y : Hex59, Z : Hex5A, [: Hex5B.
Interleave25
Interleave25 is a numeric barcode. The barcode must always contain an even number of
digits because the code represents two numbers, one number encoded in the bar and the
next number encoded in the space between the bars. There are multiple check digits that
are based on standards such as modulus 10 with weight 3 and so on. Define the font for
the 00 to 99-pattern by Hex21 to Hex7A. Start is HexAB and Stop is HexAC.
Code39
Code39 is a barcode represented in numerals, upper-case characters and symbols ($, %,
*, +, -, ., /, space). The check digit is modulus 43. The font is the same as ASCII code, with
the exception of the Space symbol. The Space is defined as !: Hex21, , : Hex2C, and _ :
Hex5F.
Code128
Code128 is a barcode that includes all ASCII characters. Express CodeA, CodeB and
CodeC with the same bar pattern. The check digit is modulus 103. As a font, ! to ~ (Hex21
to 7E) for CodeB is the same as ASCII. Space is defined as HexAE. DEL: Hex95 to
StartC: HexAB based on CodeB. Stop is HexAC.
