Lexmark Confidential until announced PCL 5 emulation: Lexmark 52 The composite bar code symbol always includes a linear component so that the primary identification is readable by all scanning technologies. Two-dimensional imagers can also use the linear component as a finder pattern for the adjacent two-dimensional composite component. The composite bar code symbol always includes a multi-row two-dimensional composite component on top of the linear component of the symbol. This composite component is for compatibility with linear and area CCD scanners, and with linear and rastering laser scanners. The following bar codes allow the addition of a two-dimensional composite component: 1 UPC-A (including +2 and +5 variants) A UPC-A bar code is divided into 4 areas: a Number system-A single digit that identifies the type of product that the following symbol represents. Digit Description 0 Regular UPC codes. 1 Reserved. 2 Weight items marked at the store. 3 National drug or health-related code. 4 No format restrictions, in-store use on non-food items. 5 Coupons. 6 Reserved. 7 Regular UPC codes. 8 Reserved. 9 Reserved. Note: The number system digit is usually printed on the left of the bar code. b Manufacturer code-A unique code assigned by Uniform Code Council (UCC) to each manufacturer or company that distributes goods. All products produced by a given company use the same manufacturer code. Note: The manufacturer code is usually printed below the bar code. c Product code-A unique code assigned by the manufacturer. Unlike the manufacturer code, which UCC assigns, the manufacturer can assign product codes to each of their products without consulting any other organization. Note: The product code is usually printed below the bar code. d Check digit-An extra digit used to verify that a bar code is scanned correctly. Because a scan can produce incorrect data, verifying that the rest of the data in the bar code is interpreted correctly is useful. The check digit is calculated based on the rest of the digits of the bar code. If the check digit is the same as the check digit value based on the data that is scanned, then the bar code is scanned correctly. Note: The check digit is usually printed on the right of the bar code. 2 UPC-E (including +2 and +5 variants) UPC-E is a variation of UPC-A that allows for a more compact bar code by eliminating extra zeros. Because the resulting UPC-E bar code is about half the size as a UPC-A bar code, UPC-E is generally used on products with very small packaging.

The composite bar code symbol always includes a linear component so that the primary identification is
readable by all scanning technologies. Two-dimensional imagers can also use the linear component as a finder
pattern for the adjacent two-dimensional composite component. The composite bar code symbol always
includes a multi-row two-dimensional composite component on top of the linear component of the symbol. This
composite component is for compatibility with linear and area CCD scanners, and with linear and rastering laser
scanners.
The following bar codes allow the addition of a two-dimensional composite component:
1
UPC-A (including +2 and +5 variants)
A UPC-A bar code is divided into 4 areas:
a
Number system
—A single digit that identifies the type of product that the following symbol represents.
Digit
Description
0
Regular UPC codes.
1
Reserved.
2
Weight items marked at the store.
3
National drug or health-related code.
4
No format restrictions, in-store use on non-food items.
5
Coupons.
6
Reserved.
7
Regular UPC codes.
8
Reserved.
9
Reserved.
Note:
The number system digit is usually printed on the left of the bar code.
b
Manufacturer code
—A unique code assigned by Uniform Code Council (UCC) to each manufacturer or
company that distributes goods. All products produced by a given company use the same manufacturer
code.
Note:
The manufacturer code is usually printed below the bar code.
c
Product code
—A unique code assigned by the manufacturer. Unlike the manufacturer code, which UCC
assigns, the manufacturer can assign product codes to each of their products without consulting any
other organization.
Note:
The product code is usually printed below the bar code.
d
Check digit
—An extra digit used to verify that a bar code is scanned correctly. Because a scan can
produce incorrect data, verifying that the rest of the data in the bar code is interpreted correctly is useful.
The check digit is calculated based on the rest of the digits of the bar code. If the check digit is the same
as the check digit value based on the data that is scanned, then the bar code is scanned correctly.
Note:
The check digit is usually printed on the right of the bar code.
2
UPC-E (including +2 and +5 variants)
UPC-E is a variation of UPC-A that allows for a more compact bar code by eliminating extra zeros. Because
the resulting UPC-E bar code is about half the size as a UPC-A bar code, UPC-E is generally used on products
with very small packaging.
