With Lightroom 4.1 I've been trying to print 2 column, 2 row contact sheets with captioned images. When I get the cell size right to include the whole caption and try to Update With Current Settings, the layout reverts to showing only a single line on the caption. If I get the layout right on the first page, subsequent pages only show a single line of the caption. My workaround is to adjust and print each page separately. This is OK for making prints, but not for making a multi-page PDF.
