UHF Interface 
 
This interface allows the Host Application to perform specific operations pertaining to 
UHF-type tags. Since these commands override the printer’s database by interfacing 
directly to the tag module, knowledge of UHF protocols and their operation is required. 
See the <STX>KuR and <STX>KuW commands for details.   
 
 
 
 
 
 
 
 
Label Formatting Mode  
 
Label Formatting Mode utilizes the current printer configuration to process all reading, 
writing, and exception processing for each tag printed. (For exception processing and fault 
handling; see the <STX>KcFH command.) The specification for RFID programming is 
contained in the data fields of the DPL label format, which instructs the printer to write and 
read data. Two Label Formatting Modes for RFID are available. While each supports auto 
increment and decrement commands for numeric (+/-), alphanumeric (>/<), or 
hexadecimal ((/)) data, they differ when a byte count specifier is added. Both RFID Label 
Formatting commands are detailed below. 
 
 
Up to six RFID operations per label are allowed.
