When using the ZPL for the RFID read, the printer will feed one RFID tag at the end of the execution. This is because the ZPL (^XA....^XZ) also represents a label. If we only want to read the RFID without feeding an RFID tag, we have to use the RFID SGD commands, e.g., a few sample commands below. Please refer to the RFID Programming Guide 3 for details.

### Specify the content to be read.
! U1 setvar "rfid.tag.read.content" "value"

### Execute the read operation
! U1 setvar "rfid.tag.read.execute"

### Get the result
! U1 getvar "rfid.tag.read.result_line1"
