Hello again groffers!
I want to thank Tadziu, Deri and Bjarni for their insights on how groff
works.
The different behaviour between measurement systems reported by Bjarni
is not something I expected, nor something that makes any sense.
Nonetheless I managed to understand a couple of new things
The groff software is tuned to the imperial measurement system (inch
etc.).
Using another measurement system:
A text line normally never touches exactly a trap but goes beyond it.
Therefore a footer starts nearer the bottom edge than the
measurement in metric (SI) units indicates.

Very good! Your example also demonstrates how setting the
vertical spacing to zero allows directly positioning the baseline
(which is the reference position for "\D" drawing commands)

Twenty-five years ago, I started running KDE just to get its screen

I hate to be that meticulous, but if you open those images with GIMP,

There's two things to consider here. One: the trap is sprung
when a line is output that reaches OR SWEEPS PAST the trap
position. If you set your trap at -2 cm, then an output
line may nevertheless still intrude into the bottom margin

I've compiled your ROFF file and I've attached the resulting PDF.
My groff version is 1.22.4. I'm on Debian 12, stable.
Not only the word footer does not show up in the same place on the two
pages, but it's not at

It is working as intended. When you say ".sp |0c" in troff,
that does not mean

Hello groffers!
I'm writing some documents that will be exported in PDF with A4 paper
size. I'm using my own macro package.
My macro package is very very simple: it's just for defining paragraphs
and titles style. Then I've decided to add an empty footer, which is
more like a bottom margin for my
14 matches
