Works, Microsoft, mailing labels - for accurate printing -make sure you have detected any blank lines after the placeholders in your word processing merge document. If you do not remove the blank lines, the first few labels will look fine, but later on the printing may gradually drift across the page. Set your top and bottom margins for .125 inch. Choose No Gaps Between Pages on the Page Setup menu. For paper height, measure from the top of one label to the top of the next label, not the height of the label itself.
