Description of problem: To dispell on the start any doubts 'locale -k LC_PAPER' on my machine happens to print height=279 width=216 which is a USletter size (for A4 that would be height=297, width=210). Despite of that if one will do, for example and on attached demo, groff -Tps -p chemstructs.pict then viewing results, or printing, on a letter paper will have the topmost structure cut in half. After a check of a generated PS this is not suprise as in it there is 'def/PL 841.89', which is an A4 paper height in Postscript points. It turns out, which if far from clear from the man page, that one can work around by doing groff -Tps -P -g chemstructs.pict which "guesses" page size and which works fine, or explicitely groff -Tps -P -pletter chemstructs.pict after which one see 'def/PL 792' as wanted here. Unfortunately it does not look that one can set a desired default. In such situation one would think that a "guessing" code should be used unless some specific paper size was requested and not something which in many locations will come up wrong. The same issues actually affects 'man' as well. Pages printed with 'man -t ...' on a letter paper are loosing a running head (which is not that obvious until one looks closer). That particular case likely can be worked around by putting into /etc/man.config TROFF groff -Tps -man -P -g instead of the current line but I do not see something similar for the general case. Version-Release number of selected component (if applicable): groff-1.18.1.1-3
Created attachment 109304 [details] sample troff code which prints too high on a letter paper
This bug not only sits as NEW for the last nine months but is also present in the current groff-1.18.1.1-5 from development series. It seems that "guessing" should be really a default with an explicit size specification as an override. TROFF command in /etc/man.config from man-1.5p-6 (development too) also does not provide a workaround but that should not be needed with groff honouring a locale information.
Groff looks for paper size in /etc/papersize file, just run "echo letter > /etc/papersize" and it should be ok.
> Groff looks for paper size in /etc/papersize file Documentation is very far from that claim. 'man groff' does not mention anything of that sort. In 'info groff', if one knows what to look for, it is possible to find: Alternatively, STRING can be a file name (e.g. `/etc/papersize'); in a format description of DESC files. So this STRING can be anything else or may not show up at all.
