TechRepublic reports: "The printer supply business is lucrative: it's estimated that companies that produce hardware, paper, ink, and cartridges make $70 billion in sales each year. Now, what was once a niche segment of the market--printer cartridge refilling--is rapidly becoming an indispensible part of the industry. As businesses and consumers find out about the less expensive and often more environmentally friendly option of getting cartridges refilled by third-party companies instead of going to the printer manufacturer, refillers are gaining ground. Currently they do about $15 billion in business annually."
