UPC A 
UPC A is a fixed-length, numeric, continuous code that employs four element widths. 
The printer supports Universal Product Code Version A, E, EAN-8, and EAN-13. Version 
A encodes 11 digits. Typically, the UPC A format starts with a number system digit, five-
digit manufacturer’s code, five-digit product code, and a check digit. The printer makes 
no assumptions about any of the codes except the check digit. The printer prints an UPC 
bar code with the 11 digits sent to it and generates the check digit. If fewer than 11 digits 
are sent, the remaining digits will be zeros. The printer prints an UPC that is about 130% 
the size of the UPC nominal standard, which provides optimal readability. 
 
UPC E 
UPC E is a zero suppression version of UPC. The printer requires that the first digit is 
zero for number system zero. If it is not zero, the bar code is not printed. The printer 
does the compression based on the compression rules for UPC E, prints an UPC bar 
code based on the 11 digits sent to it, and generates the check digit. If fewer than 11 
digits are sent, the remaining digits will be zeros. The printer prints an UPC that is about 
130% the size of the UPC nominal standard, which provides optimal readability. 
 
EAN-13 
EAN-13 is a fixed-length, numeric, continuous code that employs four element widths. 
The printer supports EAN-13, which is a superset of UPC that encodes 12 digits. 
Typically, the format starts with a number set digit, which defines how the next six digits 
are encoded. The next five digits have fixed encoding. The last is a check digit. The 
printer prints an EAN-13 bar code with the 12 digits sent to it and generates the check 
digit. If fewer than 12 digits are sent, the remaining digits will be zeros. The printer prints 
an EAN-13 bar code that is about 130% the size of the nominal standard, which provides 
optimal readability. 
 
EAN-8 
EAN-8 is a fixed-length, numeric, continuous code that employs four element widths. 
The printer supports EAN-8, which is a superset of UPC that encodes seven digits. The 
printer prints an EAN-8 bar code with the seven digits sent to it and generates the check 
digit. If fewer than seven digits are sent, the remaining digits will be zeros. The printer 
prints an EAN-8 bar code that is about 130% the size of the nominal standard, which 
provides optimal readability. 
 
EAN-14 
EAN-14 It is a high-density, fixed-length, numeric, continuous code, which employs 
multiple element widths. EAN-14, is a subset of Code 128 that encodes FNC1 and 14 
digit pairs. If fewer than 14 digits are sent, leading zeros will be added to complete the 
code. 
 
Code 93 
Code 93 is a variable-length, alphanumeric bar code. The complete data field is printed 
by the printer. Due to space limitations, only 10 characters can be printed. 
 
Codabar 
Codabar is a variable-length format, primarily used for numeric symbols. It offers 16 data 
characters, including the numeric digits zero through nine, and -, $, :, /, ., and +. Four 
unique start/stop characters, designated A, B, C, and D, are also available. Due to space 
limitations, only 12 characters can be printed.
