groff_mm(7) talks of `.PGFORM'. printf '%s\n' '.PGFORM 9i 8.5i 1i' ".PF 'left'centre'right'" `seq 3000` | groff -mm -Tpdf -P-l -P-pletter >foo.pdf You'll see page one's header is centred on the old page width compared with pages two and three. Using registers set on the command-line, before the `-mm' has effect, avoids this problem, as hinted at in groff_mm(7). printf '%s\n' ".PF 'left'centre'right'" `seq 3000` | groff -mm -Tpdf -rL=8.5i -rO=1i -rW=9i -P-l -P-pletter >bar.pdf -- Cheers, Ralph. https://plus.google.com/+RalphCorderoy
