I couldn't reproduce your problem with groff 1.23.0. I used the attached input document, very similar to yours, but combining the page layout and page content stuff. With the `pl` request commented and the `-P -pa4` option sequence omitted, I get a page that numbers 54 lines before springing the footer trap, which writes the word "footer" and breaks the page. $ groff -K utf8 -T pdf ATTIC/bini.roff >| ATTIC/bini.pdf If I uncomment the `pl` request and restore the option sequence... $ groff -K utf8 -P -pa4 -T pdf ATTIC/bini.roff >| ATTIC/bini.pdf ...I get a page that is noticeably longer, numbering 58 lines before the footer trap springs. The visible bottom margin sizes _look_, to my eyeballs, about the same size. (Once upon a time, like 25 years ago, there was a tool called xruler or similar that made it easy to measure distances on the screen. Unfortunately, I guess as parcel of "making Linux ready for the desktop", this sort of practical application was discarded as being too ugly. Didn't help with that streamlined, configuration-free experience Sun was going for by taking over GNOME development, and didn't promote TrollTech's private dialect of C++, so it got consigned to the flames.) ...but I digress. Please verify that you can reproduce the results I'm getting. If you can, we'll look into the matter of achieving precise margin sizes, an area I have recently come to feel is under-documented in groff. If you _can't_ reproduce my results, we need to sort that out; there may be a bug somewhere wanting squashing. Regards, Branden
