And this is mine:
HL3170CDW:\
:mx=0:\
:sd=/var/spool/lpd/hl3170cdw:\
:sh:\
:lp=POSTSCRIPT_P1@172.25.1.15:\
:if=/opt/brother/Printers/hl3170cdw/lpd/filterhl3170cdw:
When I use lpr to feed it a postscript file, such as the following:
%! PRINTPS.CPP PostScript OUTPUT
/cour /Courier findfont 5 scalefont def
cour setfont gsave
%54 756 moveto (cd ~/sys/web/chimera-1.65) show
%54 751 moveto (test-chimera &) show
/cm 72 2.545 div def
% In theory should use 2.54 not 2.545, but this is more accurate on my printer.
/side cm 3 div def
/ssin side 2 div def
/ccos side 30 cos mul def
/vert { 0 side neg rmoveto 0 side rlineto } def
/rise { ccos ssin rlineto } def

I get a lovely page of hexagons.
But if I try to print a pdf,
lpr grouptable.pdf
I get:
Hey! Surprise! Today it does print a pdf. last time I tried it, it
didn't. Let me hope that whatever was wrong has been fixed, and that
I'm not just lucky today.
I did change the IP number in the printcap, because the printer's IP
number has also changed (and it's now static, so I wn't have to do
this again). As far as I know, that shouldn't affect printability
pdf's, though.
