How many pages can be printed using one HP ink cartridge??

I have HP D1400 series (that uses ink cartridge number 21), and I wonder how many pages can be printed using one ink cartridge in the fast draft mode..


if you have a similar printer, please tell me...How many pages can be printed using one HP ink cartridge??
I work for a company that sells inkjets and lasers. The hp 21 should print about 190 pages. That is the standard page yield at 5% coverage. So, depending on how much you print on each piece of paper. I also had that machine before, and I would print maybe a couple pieces a day, and the ink would last about 3 weeks. Hp has really went down on the size and page yields with these new cartridges, compared to the older hp printers. I bought a lexmark and now my inkjets last about 3 months, same amount of printing.

Sorry not that easy. Depends on how much ink is used on each page and that depends on how much writing or images use the black ink on the page. A dark image could use a lot whereas a colorful image with little black or no writing would use very, very little, if any.
i have the same printer and i would say that the ink last for five months because i bought my printer in the summer and now in october the ink has finally ran out.
