The Alpha-40L RFID commands are supported with TSPL and part of ZPL printer languages.
No, it is a factory installed feature only.
The encoding process has minimal impact on the battery life.
No, a black mark is not required.
As part of the encoding process the Alpha-40L RFID printer automatically verifies that the data is successfully written to the inlay. If an encoding error is detected, the label will be overstruck and a new label encoded. Other error handling modes are also available via the LCD menu. The Alpha-40L RFID printer has auto-detect feature, each failed label prints with the overstrike pattern, and you can select the error handling mode for RFID failures via printer LCD menu.
Yes, the Alpha-40L can work with gap RFID labels.
The Alpha-40L RFID only supports UHF EPCglobal Gen2 (ISO18000-63) RFID labels and tags.
The Alpha-40L RFID printer has an RFID label calibration feature in the LCD menu which makes it very easy to setup the printer for both standard RFID labels. The calibration process feeds 3-4 labels to determine the optimal encoding position and RF power levels.
The Alpha-40L RFID printer complements the TSC mobile printer series as well as the Printronix Auto ID branded RFID printers. The durable and feature-rich mobile RFID printer boosts productivity with on-the-go printing when you need immediate and accurate RFID labels.

Thanks to intelligent TSC Smart Battery technology, users are able to gather a lot of information about battery health and understand the history of the charge cycles on their mobile printers. When in use, the smart battery is reporting the health and activity of that battery over the entire shift. It’s important in mission-critical printing to understand the device’s activity levels when it is being used non-stop over an entire shift or 24-hour period.
