Ink use depends on the model of printer and how you print. I use a Canon, but the priciples remain the same.
1. If at all possible, print edocuments as a PDF. No ink required at all.
2. Print documents as black and white. Limits ink usage to one tank.
You may need to provide more information on your printer, since some models allow additional tweaking.
In that case, you may not have much control over the amount of ink the C410a uses. Some models (like the Canon iP4300) are ink-skimpy; the majority are liberal with their ink.
Maybe I'm mind-reading, but it seems you're bothered about the cost of ink replacement cartridges. You can purchase factory ink (at premium prices), or visit eBay and look at the competition. Make certain your cartridge has the smart chip installed; that helps you monitor your ink levels. Within the year, the prices will go down, and cartridges with chips installed will be more widely available.
Ah I see. My wife uses the Ipad to print things alot and she said she notices it seems to use the "normal" in mode instead of the "Fast draft" which uses less ink. Granted it doens't say what ink mode its using. i personally don't print stuff that much since ink is costly. But yeah I'll just tell her not much we can do about it.
