RFID Programming Guide

58978L-008 Rev. A

Description   Use this command to encode the current RFID tag. Check the amount of data 
memory available for the tag that you will be using. If you send more data than the memory 
can hold, the printer truncates the data.

Format   ^WTb,r,m,w,f,v

This table identifies the parameters for this format.

The ^WT command is provided only for backward-compatibility with label formats 

that were developed for older Zebra RFID printers. Use 

 instead whenever 

possible. See 

 for the list of printers and 

firmware with which you can use this command.

b

= block  number

Specifies the block number to encode. This parameter is tag-
dependent. 

For most tags, use block 0. 

For EPC Class 0 Plus, block 0 is EPC data, and block 1 is 
user data. 

For the R4Mplus, you can encode 12 bytes (96 bits) to 
block 0, but you can encode only the first byte of block 1.

Accepted values: 0 to n, where n is the maximum number of 
blocks for the tag.

Default value: 0

r

= number of retries

Changes the number of times that the printer attempts to 
encode a particular block of a single RFID tag. (Same 
function as the 

^RR

 command.)

Accepted values: 0 to 10

Default value: 0

m

= motion

Enables or disables RFID motion. (Same function as the 

^RM

 

command.)

0 = 

Feed label after writing

1 = 

No feed after writing (other ZPL may cause a feed)

Default value: 

0

w

= write protect

0 = 

Not write protected

1 = 

Write protected

Default value: 0
