Bar Code E

Identifies the Code 128 variable length bar code with modulo 103 checksum calculation.

Code 128 can encode the entire 128 ASCII character set, including both uppercase and

lowercase alpha characters. Code 128 is an element based bar code similar to the UPC

fonts. Therefore ratios must be equal to one. The valid ratios are 1:1, 2:2, 3:3, 4:4, 6:6

and 8:8.

The Prodigy Plus

supports Code 128 Code Subset A, B, and C. You can select the

printer to start on any code subset and switch to another with the data area (default is

subset B).

Code Subset A includes all of the standard upper case alphanumeric keyboard

characters plus the control and the special characters. To select Code Subset A, precede

the data to be encoded with an ASCII A (DEC 65, HEX 41).

Code Subset B includes all of the standard upper case alphanumeric keyboard

characters plus lower case alphabetic and special characters. To select Code Subset B,

precede the data to be encoded with an ASCII B (DEC 66, HEX 42). If no start character

is sent for the 128 font, Code Subset B will be selected by default.

Code Subset C includes the set of 100 digit pairs from 00 through 99 inclusive, as well as

special characters. Code Subset C is used for double density encoding of numeric data.

To select Code Subset C, precede the data to be encoded with an ASCII C (DEC 67, HEX

43). You must not try to encode alpha data if you select Code Subset C.

Special Character Handling

Characters above ASCII value 95 are considered special characters. To access these

values, a two character reference table has been built into the Prodigy Plus

Label

Printer. The following table describes this reference.
