<ESC>Cn

Based on testing, this command works the same on the Zebra printer with 

APL-I firmware as on the 3400D printer.

When switching between 

Advanced Mode

 (default) and 

Emulation Mode

, all entered 

data is lost. Page 0 is the default page, and the field pointer selects the first field in format 0.

Purpose  To increase/decrease alphanumeric characters in a field separated domain.

<GS>

Based on testing, this command works the same on the Zebra printer with 

APL-I firmware as on the 3400D printer.

It is possible to have numerous data regions in one field as long as they do not 

overlap. Each region separately increments or decrements depending on the value entered for 
the specific field. Data length remains the same when setting values of increments or 
decrements. Values increase or decrease in a circular motion, that is, 9 increases to 0. The 

command identifies the areas of character to increase or decrease without actual changes. 
Important • 

The printer does not recognize non-alphanumeric values.

Purpose  To identify the amount of labels to print in the next batch.

<US>n

Based on testing, this command works the same on the Zebra printer with 

APL-I firmware as on the 3400D printer.

Notes  When it is used the printer, it prints a certain amount of the same label. The amount is 
calculated by multiplying the number of batches by the amount in each batch.

Important  If the amount is out of range, an error code 21 is generated.
