I bought some Avery 22830 labels, which have 9, 2-1/2-inch round labels per sheet in 3 rows and 3 columns. The labels in the middle row are centered on the page – so there is more distance from the top and bottom rows to the center row than from the top row to top-of-page, or bottom row to bottom-of-page.
Since Writer doesn’t have a template for these labels, I used “Avery Letter Size” sheet and filled out the size form. When I enter a vertical pitch that I measured on the labels, Libre Writer 3.5.7 ignores the vertical pitch and puts all 3 rows equally-spaced at the top of the page. That is, there is about 2 inches of unused space at the bottom of the page, and the center and bottom rows are mis-positioned.
How can I override this behavior and get Writer to use the vertical pitch I entered on the New - Label form?
