Can I use any ink to refill my printer cartridge?

I used to peruse on a printer ink topping off the discussion (no longer there) about individuals who top off cartridges as a business purchasing ink by the gallon or barrel. They didn't purchase separate ink for each brand and model. Somebody once revealed to me the principle contrast, when they sell topping off ink and units, is the headings that accompanied them.

My inquiry, would i be able to utilize topping off the ink from one model Canon printer (same arrangement distinctive model) to top off the ink tanks in another?
