    This tool is used to configure labels for printing.  Begin by
    choosing the &quot;new label&quot; link above.  You will then be given a list
    of configuration options for the label sheet you will be using.  The printer/label
    name should match the printing setup you will be using (e.g. Lexmark-Avery8160).
    This is just a name for your convenience and does not matter to the system.  For
    multiple printers, it may be a good idea to include the printer name in the label
    because the configuration for the same labels may vary from one printer to another.
    <br>
    <br>
    During label configuration, please enter all units in &quot;inches&quot;.  To save
    wasting label sheets, you might want to print &quot;page 2&quot; of the configuration
    screen on regular paper and hold it up to the light against your label sheet to see
    how well it matches.  For greatest flexibility, it is advised that you set the margins
    on your browser print dialogue as small as they will go and make all necessary adjustments
    from this form. NOTE:  Most measurements should be correct as measured on the label sheet
    but, because of the printer minimimum margin sizes, the top and left margins probably
    <em>will not</em> be correct.  Once you print a test sheet, adjust the top and left
    margins accordingly to move the labels to the correct relative position.
    <br>
    <br>
    Once you have the labels configured the way you want, choose the &quot;Select label&quot;
    link to proceed.  Label configurations are stored in a cookie on your computer and
    will remain for a year from their last update or until deleted.  To create a new label,
    you may begin with an existing label and change the name before choosing the &quot;Set
    values&quot; button.
