Positioning Fields

Using the IPL command language to position fields is the trickiest part of

designing labels. Since you cannot tell exactly how the field looks until it

prints, you may need to make several test prints before you get the field

positioned correctly.

For all types of fields, determine the print position by defining the

coordinates of the upper left corner of the unrotated field.

The field origin is the upper left corner of an unrotated field. To define

the coordinates of the field origin, use the origin command (oX,Y) where o

is the command that specifies origin, X is the distance from the left side of

the label, and Y is the distance from the top of the label.

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

command to set the printer for the correct label width; otherwise, the Y

origins will be incorrect.

The X and Y coordinates of the field origin use dots as their form of

measurement. There are 203 dots per inch or 8 dots per millimeter.

Note: The 3400e with 400 dots per inch, 3240, and 3440 printers have

406 dots per inch or 16 dots per mm. The 4X30 printers have 300 dots

per inch or 12 dots per mm.
