Not using d.histogram, but I would recommend taking a look
at g.gnuplot. The following shows the histograms of
two spearfish raster files in the GRASS graphics monitor:

% g.gnuplot
gnuplot> plot '< r.stats -c soils.range' w i, '< r.stats -c soils.ph' w i

then, hardcopy output is just a step (or four) away:

gnuplot> set term postscript
gnuplot> set out 'tmp.ps'
gnuplot> replot
gnuplot> !lp -dprinter tmp.ps
         (^^ or whatever command you use to print).
