A label printer applicator system programs labels having integrated circuits therein and applies the labels to a package. The applicator includes a tamp assembly having a tamp pad movement assembly and a tamp pad coupled thereto. An RF assembly, including an RF antenna, an RFID engine and antenna cable, is coupled to the tamp assembly. The tamp pad moves from a receiving position, where it receives a non-programmed label, to an extended position, where it applies the label to a package. The RFID engine provides RFID information to the RF antenna, which sends RFID information signals to the label to program the label. After the RFID label is applied to the package, the RF assembly sends test signals to the RFID label to determine whether the label has been properly programmed.
