Chapter 2 BT-1000 Barcode Font Solutions Manual

1 Code 128

1.1 About Code 128

Introduced in 1981, Code 128 bar codes are used extensively by the shipping
industry, as well as for inventory, ID, and t r acking purposes. It is often selected over
Code 39 when space is at a premium and because it offers a much lar ger selection
of characters. The Code 128 standard is maintained by AI M (Automatic Identification
Manufacturers).

Code 128 provides a very dense numeric-only bar code, and a dense alphanumeric
bar code. This is a continuous code, of variable length, bi-dir ect ional and self ­checking. It is designed to encode all 128 ASCII characters , and is optimized to
compress the bar code. It will use the least amount of space for data of 6 characters
or more of any 1-D symbol.

The character set includes the lower 128 ASCII charact ers with upper and lowercase
letters, numbers, punctuation, and cont rol codes. A check digit, determined by
Modulus 103, is placed at the end of the message before the end character, for data
integrity purposes. The symbol can be as long as necessary to store the encoded
data.

1.2 Choosing the Right Font and Size

BT-1000 includes three different fonts used to create bar code symbols of different
densities. Changing fonts alters the width of a bar code without affecting the
symbol’s height. BT-1000 supports Code set A, Code set B and Code set C.

Like any TrueType or Type 1 font, the bar code fonts can be scaled to any size. Any
of the fonts formatted at 24 or 36 points will create bar codes 1/3 (8.5mm) or ½
(12.7mm) inches tall, respectively. Print samples of your desired string in a
number of the fonts to verify that it can be scanned when printed on your
particular printer.

1.3 PCL Escape Sequences

To print from Unix or DOS systems you must send the appropriate PCL escape
sequences to print the bar code font you require. Exam ple escape sequences ar e
shown below:

Code128TT-Regular : esc(12Yesc(s1p#v0s0b28685T
Code128-NarrowTT-Regular : esc(12Yesc(s1p#v0s0b28686T
Code128-WideTT-Regular : esc(12Yesc(s1p#v0s0b28687T
(#: point size 0.25 – 999.75)

Replace the hash (#) with the relevant point size. For exam ple, to print a bar code
that is one inch (25.4 mm) high, substitute ‘#’ with ‘72’. To print a bar code half and
inch (12.7 mm) high, use 36.

To switch back to printing normal fonts in the t ypest y le you expect , print the PCL font
list from the printer contr ol panel, and r efer to the escape sequence shown on the
print out.

2 Code 39

2.1 About Code 39

Code 39 was the first alphanumeric bar code developed and is the most widely used.
Also known as Code USD-3 or Code 3/9, Code 39 is widely used in many industries
and is the standard for many government bar code specif ications, including the U.S.
Department of Defense. Code 39 is defined in Amer ican National Standards Institute
(ANSI) standard MH10.8M-1983.

Code 39 is often used for identification, inventor y, and work-in-process tracking
because the character set is alphanumeric, the input st r ing lengt h is var iable
(although more than 25 characters is hard t o accom modate), and the symbol itself
can vary in height and width. It is bi-directional, includes a checksum option, and is
discreet.

BT-1000 includes eight fonts and switching between them changes the bar code’s
width and density without changing its height.

2.2 What’s in it?

Code 39 is an alphanumeric bar code that can be as long as necessary to store
encoded data. Designed to encode 26 uppercase letters, 10 digits and 7 special
characters, the Code 39 character set includes t he digits 0-9, the letters A-Z (upper
case only), and the following symbols: space, minus (-) , plus (+), full stop (.), dollar
sign ($), slash (/), and percent ( %). It can be extended to code all 128 ASCII
characters by using a two character coding scheme. Extended characters are
encoded by a pair of normal Code 39 characters; for exam ple, a lower case 'a' (not
part of the standard Code 39 character set ) can be encoded by t he pair '+A'. A
carriage return control code can be encoded by the pair '$M ' .

The symbol includes a quiet zone, the start character " * " , the encoded data, the stop
character "*", and a trailing quiet zone. The ast er isk in code 39 is used as t he st art
and stop bar. 5 bars and 4 spaces for a total of 9 element s r epr esent each character.
Each bar or space is either "wide" or "narrow" and 3 out of the 9 elements are
always wide. That is what gives the code its other name - Code 3 of 9. Of the 9
elements, 3 are large and 6 are narrow. Characters are separated by an inter­character gap the same width as a narrow bar. The ratio of wide: narrow bar width
may be in the range of 1.8 to 3.4. Bar codes wit h a narrow bar width of less than

0.020 inches (0.508mm) should have a ratio of at least 2.5. A ratio of 3.0 is
recommended. Every Code 39 bar code should be preceded and followed by a quiet
zone the width of at least 10 narrow bars.

10

2.3 Choosing the Right Font

The various Code 39 fonts creates bar code symbols of differ ent sizes and densit ies.
Most of the fonts use a 2.5:1 wide: nar r ow bar ratio. The Slim fonts use a 2:1 ratio for
narrower symbols and the Wide font uses a 3:1 ratio f or wider symbols. Like any
TrueType or Type 1 font, the bar code fonts can be scaled to any size. Any of the
fonts formatted at 24 or 36 points will create bar codes that are 1/3 (8.5mm) or 1/2
(12.7mm) inches tall respectively.

Be sure to print samples of the desired string in a num ber of the fonts and check that
it can be scanned when printed on your particular printer. Since t he fonts have
different wide bar to narrow bar r a t ios, and over all height to width ratios, the same
string formatted in differ ent f onts will be different widths. Try differ ent fonts to decide
which one works best in your situation.

2.4 The PCL Escape Sequences

From UNIX or DOS it is necessary to send PCL escape sequences as part of the
print data to select the desired bar code font. Example escape sequences are shown
below:

Code39QuarterInch-Regular : esc(9Yesc(s1p#v0s0b28676T
Code39HalfInch-Regular : esc (9Yesc(s1p#v0s0b28677T
Code39OneInch-Regular : esc(9Yesc(s1p#v0s0b28678T
Code39SmallLow-Regular : esc(9Yesc(s1p#v0s0b28679T
Code39SmallMedium-Regular : esc(9Yesc(s1p#v0s0b28680T
Code39SmallHigh-Regular : esc(9Yesc(s1p#v0s0b28681T
Code39Slim-Regular : esc(9Yesc(s1p#v0s0b28682T
Code39Wide-Regular : esc(9Yesc(s1p#v0s0b28683T
(# : point size 0.25 - 999.75)

Replace the hash (#) with the relevant point size. For exam ple, to print a bar code
that is one inch (25.4 mm) high, substitute ‘#’ with ‘72’. To print a bar code half and
inch (12.7 mm) high, use 36.

After printing a bar code it is necessary to select a dif ferent font in order to print
something besides more bar codes. The PCL command to select the default font is
“<esc>(3@”. To select a font other t han the default font, use the PCL escape
sequence show on the PCL font list. The “<esc>” shown is the ASCI I escape
character. It is decimal 27, hexadecimal 1B, oct a l 33, or binary 00011011.

4 UPC / EAN Code

4.1 About the UPC / EAN Code

UPC Code is a collection of Type 1 and TrueType fonts that create and pr int UPC
version A, UPC version E, EAN-8/JAN-8, EAN-13/JAN-13, Bookland (ISBN), and
ISSN bar code symbols within any Microsoft Windows
The bar code fonts in UPC Code can be used with your database, spreadsheet, or
custom application by simply changing fonts.

Created in 1973, UPC is perhaps the best-known and commonly used 1D bar code.
The similar European Article Numbering (EAN) and Japanese Article Numbering
(JAN) codes were developed soon after. Extr em ely r eliable codes, (version A of UPC
has a 99 percent success rate on the first read pass of a fixed laser scanner) they
use the relative distances between leading to leading, and trailing t o trailing edges of
bars to decode the symbols. It is suitable for a variety of printing techniques and is
not prone to errors from ink spr eading dur ing pr inting.

UPC, EAN, Bookland, and ISSN bar codes are found on reta il it em s scanned at the
cash register. Package designers therefore creat e these bar codes. UPC symbols
are also placed on shipping labels, forms, and catalogs. Book covers have a
Bookland bar code based on the ISBN number. EAN and JAN bar codes are used
outside of the US and Canada, while international periodicals use ISSN bar codes.

Generally, the code is split into two halves of six digits each. The first one is always
zero, except for products like meat and pr oduce t hat have variable weight, and a few
other special items. The next five are the manuf acturers’ code, the next five are the
product code and the last is a check digit used to verify that the preceding digits
have been scanned properly. Cues in the structure of the code tell the scanner which
end is which, so it can be scanned in any direction.

Both UPC-A and UPC-E allow for a supplemental two or f ive digit number to be
appended to the main bar code symbol. The supplemental message was designed
for use on publications and periodicals. To enter a supplemental m essage, it must
consist of either two or five numeric digits . The supplem ental is simply a small
additional bar code that is added onto the right side of a standar d UPC sym bol.

4.2 Types of UPC Symbols

4.2.1 UPC-A

UPC-A is a 12 digit, numeric symbology used in retail applicat ions t o identify the
manufacturer and specific product so point-of- sale cash register systems can
automatically look up the price. UPC-A symbols consist of 11 data digits, and one
check digit. The first digit is a number system digit that usually represents the type of
product being identified.

The next 5 digits are the manufacturers ’ code, f ollowed by a 5-digit product code.
UPC-A encodes 12 numeric digits. The first digit identifies the numbering system:

0: regular UPC codes
1: reserved
2: random weight items marked at t he st ore
3: National Drug Code and National Health Related Items code
4: no format restrictions, f or in- s t or e use on non-food items
5: for use on coupons
6: reserved
7: regular UPC codes
8: reserved
9: reserved

The next group of 5 digits identifies the manufact urer and is assigned by The
Uniform Code Council (UCC). The next 5 digits ident if y the particular product and are
assigned by the manufacturer. The last digit is a Modulo 10 checksum.

The checksum is a Modulo 10 calculation.

1. Add the values of the digits in positions 1, 3, 5, 7, 9, and 11.

2. Multiply this result by 3.

3. Add the values of the digits in positions 2, 4, 6, 8, and 10.

4. Sum the results of steps 2 and 3.

5. The check character is the smallest number which, when added to the result in
step 4, produces a multiple of 10.

A UPC-A code may be augmented with the two-digit supplem ent al bar code noted
above to indicate the issue number for a periodical. Weekly publicat ions ar e
generally numbered 1-52, while semi-monthlies are num ber ed 1-24 and monthlies 1-

12.

4.2.2 UPC-E

The UPC-E code is a compressed bar code intended for use on small item s.
Compression works by squeezing extra zeros out of the bar code and t hen
automatically re-inserting them at the scanner . Only bar codes containing zeros are
candidates for the UPC-E symbol.

UPC-E is also referred to as "zero suppressed". The way this works is that UPC-E
compresses a normal 12-digit UPC-A code into a six-digit code by " s uppr essing" the
number system digit, trailing zeros in the manufacturers code and leading zeros in
the product identification part of t he bar . By suppressing zeros, UPC-E codes can be
printed in a very small space required for labeling small items. The UPC-E code can
only be used if the system character is 0 and the original 10 data characters have at
least four zeros.

For example, the UPC-A code 12300-00064 can be compressed to 123643. The last
digit (3) indicates the type of compression. Guard bars precede and follow the data
in the pattern. The UPC-E bar code specifies left hand guard bars, the six data
characters, and right hand guard bars.

In addition to the requirement that the first digit of t he bar code (number syst em)
must be zero, there are four rules that determine what UPC codes can be printed
using the compressed UPC-E format:

*If the last 3 digits of the manufact ur er's number are 000, 100, or 200, the valid
product code numbers are 00000 - 00999 (1,000 numbers)
*If the last 3 digits of the manufact ur er's number are 300, 400, 500, 600, 700, 800, or
900, the valid product code numbers are 00000 – 00099 (100 numbers)
*If the last 2 digits in the manufactur er 's number are 10, 20, 30, 40, 50, 60, 70, 80, or
90, the valid product code numbers are 00000 – 00009 (10 numbers)
*If the manufacturer's number does not end in zer o, the valid product code numbers
are 00005 - 00009 (5 numbers)

The checksum for the UPC-E code is calculated with the same method as the UPC­A code.

4.3 PCL Escape Sequences

From UNIX or DOS it is necessary to send PCL escape sequences as part of the
print data to select the desired bar code font. The PCL escape sequences for the
fonts are shown on the PCL font list. Inst ructions on how to print the PCL font list are
given in your printer manual.

Font Name PCL Escape Sequence
UPCTall : esc(24Yesc(s1p#v0s0b28688T
UPCTallNarrow : esc(24Yesc(s1p#v0s0b28689T
UPCTallThin : esc(24Yesc(s1p#v0s0b28690T
UPCHalf : esc(24Yesc(s1p#v0s0b28691T
UPCHalfNarrow : esc(24Yesc(s1p#v0s0b28692T
UPCHalfThin : esc(24Yesc(s1p#v0s0b28693T
UPCTallMusicThin : esc(24Yesc(s1p#v0s0b28694T
UPCHalfMusicThin : esc(24Yesc(s1p#v0s0b28695T
UPCTallBarsThin : esc(24Yesc(s1p#v0s0b28696T
UPCHalfBarsThin : esc(24Yesc(s1p#v0s0b28697T
(# : point size 0.25 - 999.75)

After printing a bar code it is necessary to select a dif ferent font in order to print
something besides more bar codes. The PCL command to select the default font is
“<esc>(3@”. To select a font other t han the default font, use the PCL escape
sequence shown on the PCL font list.

5 Codabar

5.1 About Codabar

Created in 1972, Codabar was developed by the Monarch Marking Syst em s division
of Pitney Bowes, Inc. Originally developed for r etail price labeling, Codabar is a
general purpose bar code used primarily for numeric data. It is used in libraries, to
label photo-finishing envelopes, Federal Express air bills, and is the American Blood
Commission's standard symbology for blood bag labeling. Blood banks use the D
stop character to indicate that the next bar code beginning with a D should be
concatenated with the current bar code. The Xer ox Codabar bar code f ont is the
Rationalized Codabar variant. Codabar may also be referr ed t o as Am es Code,
USD-4, NW-7, or 2 of 7 Code.

Codabar is bi-directional, self-checked and discrete. Its length is unlimited and there
is no checksum defined as part of the Codabar standard, but some industries
(libraries, for example) have adopted their own checksum standards. AIM has a
recommended check character.

The Codabar font works with any Microsoft Windows
application. As a font, it is easy to integrat e int o a database, spreadsheet, or custom
application.

Codabar is unusual because some characters are wider than other s. With 2-element
widths defined, each character contains 4 bars and 3 spaces. The charact er is
followed by a single narrow space to separate it from t he next character. Each
pattern begins and ends with one of 4 start/stop characters A-D.

Codabar defines different element widths f or each of the characters in an effort to
make all the characters have the same width. ( Rat ionalized Codabar uses the same
patterns, but assigns only 2 element widths for wide and narrow.)

5.2 PCL Escape Sequences

From UNIX or DOS it is necessary to send PCL escape sequences as part of the
print data to select the desired bar code font. The PCL escape sequences for the
fonts are shown on the PCL font list. Inst ructions on how to print the PCL font list are
given in your printer manual.

Font Name PCL Escape Sequence
Codabar-Regular : esc(26Yesc(s1p#v0s0b28702T
(# : point size 0.25 - 999.75)

Replace the hash (#) with the relevant point size. For exam ple, to print a bar code
that is one inch (25.4 mm) high, substitute ‘#’ with ‘72’. To print a bar code half and
inch (12.7 mm) high, use 36.

After printing a bar code it is necessary to select a dif ferent font in order to print
something besides more bar codes. The PCL command to select t he default font is
“<esc>(3@”. To select a font other t han the default font, use the PCL escape
sequence show on the PCL font list. The “<esc>” shown is the ASCI I escape
character. It is decimal 27, hexadecimal 1B, oct a l 33, or binary 00011011.
