Label Formatting Command Functions
Class Series Programmer’s Manual 121
U Mark Previous Field as a String Replacement Field
This command controls the way replacement data is formatted. Specifying a field as a string
replacement for dynamic fields, and not for static fields, will optimize label throughput. See the
<STX>U
command.
 Note: The length of the original string sets the data string length of any replacement; both must be equal.
The data being used when created must be valid for the font type being selected.

The sample sets up the label format for register loading and prints two labels. The first two of the four
format records have been designated as replacement fields. The second label is generated with
System-Level field-replacement commands and prints the last label.
X Terminate
Label Formatting Mode
This command causes the printer, when in label formatting mode, to immediately switch to the
system command mode and generate a label format based on the data received at that point. However,
unlike the ‘E’ command, it will not print a label. (Other termination commands are the ‘E’ and ‘s’.)
