^KC – Set Client Identifier (Option 61)

What ^KC does

^KC is part of the Network Commands reference. Use it when working with set client identifier (option 61) 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

^KCa,b,c,d

Parameter quick reference

• a = enable or disable Values:
• 0 = disable (default)
• 1 = enabled, use MAC address
• 2 = enabled, ASCII value
• 3 = enabled, HEX value
• Default: 0
• b = device Values:
• 0 = all devices
• 1 = wireless
• 2 = external wired

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.
