Arthritis of the Foot and Ankle. The pain and stiffness you feel in your feet and ankles as you grow older could be arthritis. If left untreated, this nagging pain can grow worse, eventually becoming so excruciating that you can no longer walk even short distances.
Black and white copies are $0.08 per side so a 300 page B&W copy on standard 28# white bond paper would be $24.00 plus tax. Double sided would be twice that. Color copies are $0.89 per side so 300 pages single sided on #28 white paper would be $267.00 plus tax. Double sided would be $534.00. Personally, I would advise against color copies.
Add the color cost per page, $0.101 cents, to the monochrome cost per page, $0.028 cents, and you have a total cost per page of $0.129 cents. Toner page yield varies widely, but the HP 126A is a more spendy one. As Melissa Riofrio at PC World points out, more expensive printers usually mean more expensive toner.
