Questions about this item

What does the 300 dpi resolution mean for label quality on my SG112-EX?

It produces 300 dots per inch, giving sharp barcodes, small text and fine graphics on thermal labels without needing a higher-density head.

How does the printhead connect to the SG112-EX and what limits does that impose?

It mounts directly into the SG112-EX print carriage using the factory connector, so the only limits are the printer's maximum print width and speed settings.
