Using Option 21 (Define Extended Field Names); Using Option 30 (Pad Data); Sample Use For Padding - Avery Dennison ADTP1 Reference Manual

U s i n g O p t i o n 2 1 ( D e f i n e E x t e n d e d F i e l d N a m e s )
This option defines names for each field in a format, which can be longer than eight characters.
This option is only available on the XML-enabled printer.
Syntax
R,21,"field_name" |
R1. R
R2. 21
R3. "field_name"
Example
T,2,10,v,250,50,0,1,1,1,B,C,0,0,0 |
R,21,"SALEPRICE_FIELD" |
Defines the name for text field 2 as "SALEPRICE_FIELD."
U s i n g O p t i o n 3 0 ( P a d D a t a )
Add characters to one side of a field to "pad" the field. Padding fills in the remaining spaces when
entered data does not fill an entire field. If a variable length field is not completely filled with
batch data, this option fills the remaining positions in the field with the character designated by
Option 30.
Note: Option 30 can be applied to an RFID Data Field.
Syntax
R,30,L/R,"character" |
R1. R
R2. 30
R3. L/R
R4. "character"
Example
R,30,L,"X" |
Pads data with an "X" on the left side of the field.
Example
X,2,24,0 |
R,30,R,"0" |
Pads the data in the RFID Data Field with a "0" on the right side of the data. This example uses
a 96-bit RFID inlay.

Sample Use for Padding

Use pad characters to make a variable length bar code occupy a fixed amount of space on the
supply. If the maximum number of characters in the bar code is 15, but the batch packet only has
10 characters, the padding option fills the remainder of the field with pad characters.
