Example • This example sets the printer to move the media to 800 dots from the top of the
media [or label length - 500 from the bottom (leading edge) of the media] and prints “void”
500 dots in vertical length (Y axis) in case of an error.

Figure 29 shows the resulting voided label. Note where the void starts. The media has been
moved 800 dot rows from the top of the label [label length minus 800 dot rows from the
bottom (leading edge) of a label] to bring the transponder into the effective area to read/write a
tag. If the printer fails the operation, an area that is 500 dot rows of the media is voided instead
of the entire rest of the media as in Figure 28.
