It's possible that printer companies are using tech to keep ink profits up. Whatever the truth of the matter, you may want to check your favorite news search engine before buying for reports about your prospective printer.
You do have to be careful: badly-made cartridges can result in poor-quality text and printer damage. However, a good recommendation to a reputable firm could save you a lot of money. Another option is refillable ink cartridges. Some people swear by them, but I would be cautious -- the possibility for leaks is, in my opinion, not worth the risk.
What is that? That is the number of pages that a typical ink or toner cartridge may be expected to produce. Most manufacturers estimate their yields based on coverage of about 4 or 5 percent -- in other words, about 4 or 5 percent of the printed page will actually have ink on it. So an ink cartridge that has a yield of 450 based on 5 percent coverage should be expected to print out about 450 pages assuming that each page has about 5 percent of its surface covered by the ink.
This means, of course, that if you tend to print pages that have a great deal of text on them, or that use images, or that use a great deal of bold lettering -- your results will vary greatly.
For example, take a typical inkjet printer like the Epson Stylus C84, which costs under $100. An Epson black ink cartridge that yields (according to the manufacturer) about 450 pages runs about $25. The same printer uses four color ink cartridges, each of which cost about $15 for a yield of about 420 pages. (Keep in mind that you color ink coverage, especially if you're printing photographs, is probably going to be much higher than the 5 percent that the 420-page figure is based on.)
Unfortunately, there are few independent sources that can tell you the true yield for each printer out there. As a result, we have to rely on the manufacturers' figures. But even using those as a guide, you can figure out which printers will cost you more in the long run.
