2 Determine the placement of each field from the label origin. The label

origin (oØ,Ø) is the top left corner of the label.

• To determine the horizontal or X origin of each field, measure the

distance from the left side of the label to the upper left corner of the

field.

• To determine the vertical or Y origin of each field, measure the

distance from the top of the label to the upper left corner of the field.

Note: On the 4400 and 7421 printers, be sure to use the label width

command to set the actual width of your labels; otherwise, the Y

origins will be incorrect.

When you combine the two numbers, they form the field origin oX,Y.

In the illustration below, the horizontal or X origin of the human-

readable field measures 12.7 mm (0.5 in) from the left side of the label

and the vertical or Y origin measures 6.35 mm (0.25 in) from the top of

the label.

3 Convert the measurements for the human-readable field from inches to

dots. Use this equation:

25.4 mm (1 in) = 203 dots

1 mm = 16 dots

In this example, the human-readable field origin in dots is:

12.7 mm (0.5 in) x 203 dots = 102 dots (X dimension)

6.35 mm (0.25 in) x 203 dots = 51 dots (Y dimension)

The origin for the human-readable field is o102,51 (oX,Y).
