^SL – Set Mode and Language (for Real-Time Clock)

What ^SL does

^SL is part of the Printer and Media Control reference. Use it when working with set mode and language (for real-time clock) on compatible Zebra printers. This independent reference focuses on the command shape, configuration inputs, defaults, and the surrounding commands that are commonly used with it.

Syntax

^SLa,b

Parameter quick reference

• a = mode Values:
• S = Start Time Mode. This is the time that is read from the Real-Time Clock
• T = Time Now Mode. This is the time that is read from the Real-Time Clock
• Numeric Value = With the Enhanced Real Time Clock (V60.13.0.10 or later)
• SL30,1 = Accuracy tolerance of 30 seconds and use English.
• Default: S
• b = language
• Values:
• 1 = English
• 2 = Spanish

Implementation guidance

• Confirm that the printer model and firmware support the command before deployment.
• Test the smallest valid command first, then add optional parameters one at a time.
• Keep units in printer dots unless the command explicitly defines another unit.
• Verify the result on the target media, because resolution, orientation, and stored settings can change the output.

Troubleshooting

If the printer ignores the instruction, check the command prefix, delimiter characters, firmware support, and whether the command belongs inside a ^XA and ^XZ format. For output commands, also confirm that the field is closed with ^FS where required.
