For HP inkjet printers:
If you only paid for the ink, bulk ink is around $1.35 USD per ounce if
bought in a 32 oz bottle of black ink. A 45 cart is 42 ml or about 1.4 oz
per refill or about $1.89 per refill.
For the 23 cart, Color ink is about $1.25 USD per ounce per color if bought
in 8 oz bottles.
A 23 cart is 10 ml per color so about 1/3 oz per color or $0.42 per color
times 3 colors = $1.26 per refill.
For the 78 cart, Color ink is about $1.50 USD per ounce per color if bought
in 8 oz bottles.
The large 78 cart is 38 ml total, or about 12.5 ml per color. Or less than
1/2 oz per color, so about $0.75 per color times 3 colors = $2.25 per
refill.
If you have the 45 and 23 carts.

Refilling is a messy job, but you can save some money, You can get at least
3 refills of a color cartridge, and many refills of the Black cartridge.
You do not even have to refill your own cartridges, the above company will
do it for you.
With the HP cartridges you also get a new print head each time you put in a
new cartridge.

I'm not talking about individual ink tanks here. When I quoted that
price per/gallon,
I was referring to the big picture which included all ink tanks bought
new.
I got that info. from a website offering bulk ink and refill services.
As for Refilling being messy, wear latex gloves. It doesn't have to be.
After you get used to it, it's quite simple.
I've been doing mine now for some time and wouldn't have it any other
way.
I do realize though, that it's not for everyone, but considering the
prices out there
for OEM tanks, something has to be done.
Take for example where I live, A Canon tank for my Printer is about
$20.00
I can now buy a generic tank for half of that...and I don't see much
difference in the printing...
