How to use
Turn off the label printer before replacing the tape cartridge. Open the printer’s tape compartment, remove the spent cartridge, and insert the new 12 mm tape cartridge according to the device’s alignment guides. Close the compartment, power on the printer, and advance the tape or perform a test print to ensure correct installation. Use the label printer’s controls or software to set text size, font and margins appropriate for a 12 mm label.
Usage recommendations
For best results, keep the tape and printer in a dry indoor environment and avoid prolonged exposure to direct sunlight. Test a sample label for font size and alignment before producing multiple copies. Use the tape for general identification tasks where a clear black-on-white label is required; for outdoor or heavy-wear applications, consider specialized tapes designed for enhanced weather or chemical resistance.
