Differences in screen and printed plots

[JuanPi]

Hi all,

Since a while I have been suffering the difference between what we get
in the screen when we plot (really nice lately!) and what we get when
we use print or saveof.

Disregarding the visual differences (sometimes I just take
screenshots!) ther eis this bug, that was gone and now is back again

This code

plot(rand(1,10), '-k', rand(1,10),'og','markerfacecolor','g');

looks like this in screen

and like this when printed

to fix it I do

set(gca,'color','none')

and print again obtaining

but then if I add a legend the legend is also wrong, and I need to do
the same to the legend axes to fix it

What is causing these bugs to re-appear? Is it gnuplot or us?

Thx!
