You have created a custom part label, but when you
print the labels, an extra blank label is printed at the beginning or end of
the series of labels.
If the label contains group header bands, set the
GroupHeaderBand property "KeepGroupHeader" to False.
Adjust the databand height property downward by
small increments until the blank page is eliminated. Be careful not to change
the height too much, or the label may print off-center.
If the label contains a group header band, set the
GroupHeaderBand properties "New Page Before" and "New Page
After" both to False.
