Hi Chris, I think the following may explain your observed behaviour.

In that case, would it not need to be placed at the page origin? (Top left of page, (0,0) in absolute gtroff page co-ordinates)? Your sample markup > ... > .tl > .vs 12.7p > .PSPIC -I 0 letterhead.eps attempts to place it the height of one title line lower down on the page, and if it needs the full page length, it clearly doesn't fit on the first page below this point, so gtroff introduces a page break, to accommodate it on the second page, which it promptly fills all the way to the bottom. You then follow it with > .sp -29.71c which causes a break, moving the output point to the *next* available text base line. Since you were already at the bottom of page 2, this break moves you to line 1 on page 3, whence you then attempt to move up a distance equivalent to one page length. However, an upward motion can never go beyond the physical top of the current page, so you end up at the top of page 3, for the start of your document content. You might try setting an arbitrarily long initial page length, (> the height of the bounding box), before you place the image, which you should place before *anything* else which emits page content, (i.e. before the .tl). Then, move back to the top of the page 'sp |0 *before* setting the real page length for formatting the document. HTH, Keith.
