In groff, the page size for
gtroff and for output devices are
handled separately. See Page Layout, for vertical manipulation of
the page size. See Line Layout, for horizontal changes.
A default paper size can be set in the device's DESC file. Most
output devices also have a command line option -p to override
the default paper size and option -l to use landscape
orientation. See DESC File Format, for a description of the
papersize keyword which takes the same argument as -p.
A convenient shorthand to set a particular paper size for
is command line option -dpaper=size. This defines string
paper which is processed in file papersize.tmac (loaded in
the start-up file troffrc by default). Possible values for
size are the same as the predefined values for the
papersize keyword (but only in lowercase) except
d7. An appended ‘l’ (ell) character denotes
For example, use the following for PS output on A4 paper in landscape orientation:
groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps
Note that it is up to the particular macro package to respect default page dimensions set in this way (most do).
