Many print applications may not require labels that fill the entire printable area of the printer. Therefore it is
important to understand how to calculate print size so that the printed image does not exceed the label size.

There are two axis to consider when calculating for print position; horizontal and vertical. The horizontal axis is
lateral positioning parallel with the print head and is measured from the right side of the media to the left. The
vertical axis is the label length from the front to its rear.

This juncture point of the horizontal and vertical axis is referred to as the Base Reference Point (or zero point) and
all measurement is incremental along those axis’ from there. The allowable ranges for these references is
dependent on the particular printer to accomodate different print widths and resolutions.

The A1 command is the prefered method of configuring the printer for media size. If using media smaller than the
print head width, use this command to specify the media size and adjust the start position corresponding to that.
The backing paper must be included in media size considerations. This command would be as follows:

Before beginning to send code, one must perform some simple calculations to determine print positioning. Firstly,
determine the print resolution and maximum print width of the printer. This information is provided in the Technical
Data unit of the Operator Manual and Service Manuals.

The print resolution of the print head has a direct bearing on the “dots per inch” (DPI) of print density. The
corresponding formula for a 203 Resolution print head on a printer with 4.1 Maximum Print Width would be: 

Once this is done, one must calculate the label width in linear dots. That formula would be as follows for a 2 inch
wide label:

Lastly, one must calculate the horizontal distance to offset printing to accomodate for the difference in size from the
printer’s maximum printable width to the label width. That formula would be as follows using the above examples:

Maximum Printable Width (Linear Dots) - Label Width (Linear Dots) = 
Print Offset (Linear Dots)

832 (Linear Dots) - 406 (Linear Dots) = 426 (Linear Dots)

In the above example, 426 would be the required command entry to reset the initial base reference point (or zero
point) to the new base reference point (or zero point) based on the label’s width.

Note that with each additional horizontal or vertical adjustment, the New Base Reference Point will always be
positioned relative to the last base reference point - not the Initial Base Reference Point. In other words, the only
way to return to the Initial Base Reference Point is to either commands to reverse the prior commands or to delete
all positioning commands to return the printer to its default state.

NOTE: The valid ranges for each of the above may be found in the product
manuals.
