📌 Printing tip: set "Scale" to 100% / Actual size, do NOT choose "Fit to page" (scaling is the main reason cells drift). Set margins to "None" if possible; if your printer doesn't support it, use "Safe margin in cell" above to inset the QR/text so edge trimming won't cut into content. Test print on plain paper first, then overlay it on the label sheet to check alignment.
