Print layout
Use a negative “down” value to pull the printing up if it lands too low on the label. Only affects printing, not the design.
For thermal label printers. Set the printer's paper size to the page size shown above.
When printing, set scale to 100% (Actual size) and margins to None.
Prints the label outline with a millimetre scale on it. Measure what comes out to check the label size and the print position against the real tag.
Hold a ruler against this bar. If it does not measure 50 mm, type what it really measures and press Apply — the designer then shows true size at 100% zoom. This only changes what you see on this computer; printed labels are always the real size.
