'Fine print' doesn't allow to reduce the 'quantity' of ink ('saturation' or
'lightness' of the black color...).
And actually I don't know any printer manager (free) that is able to do
this... If you know I'll give a try.

But trying to edit and install an icc file
is very interesting to me... :

I saw from Windows 10 'Control Panel'>'Color Manager'
that my HP printer uses two .icc files
(one for Black&White and another for Color).

I duplicated the Color file, opened it with an editor called 'Delcotec'
and tried to change what I think is the black value.
Then saved the new .icc file and installed it in Windows 10.

Then from the Windows 10 'Color Manager' panel
I told the HP printer to use this new .icc file (telling it is the default
profile now),
I printed a testing page but nothing has changed :-( .

Note:
I also duplicated the Black&White icc file
and tried to edit it,
but I was not able to find and change the black value.

Sorry I cant help much - and moved to laser printing years ago!
Would the old InkSaver software I remember from 15-20 years ago get you
anywhere? I think that allowed you to manipulate the separate ink
colours. C+

I solved the problem?
In what manner? I have missed something... :-)

I searched...
I tried InkSaver, it installs on windows 10 but when lounched it hangs.

I tried GreenCloud... it installs very well and it does what it promises:
among the other features it has three setting levels to reduce the ink
(black or color) you are going to print, and they work; tried a couple of
pages... not bad till now.
But the full version is 19.00 USD

I think I'll try FinePrint you suggested, just for a comparision.
The descrition on its web site tells it has three setting levels to reduce
the ink too.
It is not freeware.

If anyone knows similar software he can suggest too,
but as far I have seen, there are not so many software
(for Widows 10 and able to reduce the ink level before printing,
and maybe free...)

I'm also waiting for Andreas to explain the method he pointed out
(Andreas are you suggesting me to use only the color cartridges?
If so, it is not a good way because the color cartridges are more expensive
than the black one...)

PS:
I'm still searching for an help on how to manage the .icc printer profile
files....

You wrote yesterday (depending on your timezone ;-):

| I noted this:

| color inks to "imitate" the black color
| | the printer itself warns and asks: "The black ink is over, do you want

"keeps on printing, with good result" sounded like the problem was solved.

yes this is true, but...
i don't want to use color cartridge
because they are more expensive than black cartridege

(as i told you 26 monday... :
"it will not be the solution I like,
because black cartridge is less expensive
than color cartridge.")

Then I misunderstood the "save black ink" from your first article. I
assumed you wanted to use the colour cartridges to print "black".

"Draft"was already mentioned, while you say you don't see a difference to
"normal". Are there DPI settings? Crank it down to the lowest, like 150
to see if that is better.

no, there is no dpi setting
(no from software neither from printer's little display)
