How to use

Install the Citizen CL-S621II on a stable surface near a power outlet and the host device. Open the Hi-Lift™ mechanism to load label or receipt rolls and, for thermal transfer mode, install the ribbon according to the user guide. Connect the printer via the RS-232 serial port and configure driver settings on your POS or label software to match the 203 x 203 DPI resolution and desired print width. Use standard media rolls within the specified dimensions and test print to verify alignment and print quality before regular operation.

Usage recommendations

For consistent results, use media and ribbons recommended by the manufacturer, keep the media path and printhead clean, and perform routine checks of ribbon tension and roll alignment. When switching between direct thermal and thermal transfer modes, confirm software settings and perform a test print to ensure correct print mode and density.
