Robert Krulwich/NPR. Add all of us up, all 7 billion human beings on earth, and clumped together we weigh roughly 750 billion pounds. That, says Harvard biologist E.O. Wilson, is more than 100 times the biomass of any large animal that's ever walked the Earth. And we're still multiplying.
Paper. The average price for 20 lb printer paper seems to run between $4 and $6 dollars for average quality paper, so we will use $5 for 500 sheets-or a penny a page, for both inkjet and laser printers. This is the type of paper used to print text, or text with some basic business graphics.nk for the Deskjet costs $15 for the black 60 cartridge, with an estimated page yield of 200 pages. The tri-color cartridge is $20, and has an approximate yield of 165 pages. Cost per page of black text is $15.00/200: $.075, or 7.5 cents a page for text.
Print Speed: Do you need your printer for your home, home-office, or business? Top-rated printers can pump out approximately 15-19 pages per minute, without breaking stride â even on wireless networks. Inkjet vs Laser: If printing color photos at home is your priority, opt for an inkjet. If you are a business and text is more your speed, a laser printer will be for you. Just be sure to choose from one or the other for the highest quality printing.
