EPSON — 4.3.2 Media layout setting

 The limitations if the gap between labels is set to less than 3 mm are shown below.  If the gap between labels is set to less than 3 mm, both the gap between labels and the length are rounded down to the nearest 32-dot unit at a conversion of 1200 dpi. For this reason, there will be a maximum difference of approximately 0.7 mm in the set gap between the labels and distance between prints, and between the set length and print length, respectively.  If enabling the printer control software to set a gap between labels of less than 3 mm, it is recommended to inform the user that the distance between prints and print length will change, and of those values.
