When you Create A Mailing Label Template you are able to set the dimensions for your labels on step 2: Layout. When you print the PDF file on to your label paper, it is possible that the text does not line up properly on the label paper. This is caused by some print settings within Adobe Reader. Adobe Reader wants to ensure your text prints on the paper without running over. Because a couple of the print settings are set to Auto that causes the dimensions specified within eTapestry to be ignored.
