Measure two reference positions on one axis, plus an optional middle position. Compare the result with a tolerance chosen for your label stock. Use this to diagnose a plain-paper proof before changing the template or loading labels.

Measure matching reference centres from the same sheet edge. Use a ruler precise enough for the chosen tolerance. The reference is for plain paper: print at Actual Size / 100%, then measure the line.
How to use the result
The model compares two positions as measured = scale × expected + offset. A middle point checks whether that simple model explains the page. Check the paper size, template and Actual Size setting first. A small sample cannot prove printer accuracy or justify applying a correction automatically. Print the reference on plain paper at 100% and measure it before using labels.
Use known marks instead of estimating label edges
Download the two-axis control PDF. Page 1 is A4; page 2 is US Letter. Print only the matching page at 100%. Its three horizontal marks are centred at 20, 100 and 180 mm from the left sheet edge. Enter your measured positions, not values measured from a screen preview.
For a transparent calculation check, enter expected 20 / 100 / 180 and measured 19.4 / 97 / 174.6 mm: the fitted scale should be 97%, offset 0 mm and middle residual 0 mm. This numerical fixture demonstrates the model, not a printer’s accuracy. Compare offset, scale and nonlinear examples.

A part-used label sheet is not an ordinary blank sheet
I would avoid feeding a part-used sheet back through the printer unless the exact label and printer instructions explicitly support it.
