typically, printing at home costs between $1.00 and $2.00 for an 8x10 depending on your printer (pigment vs dye) and the quality of paper (staples vs red river). The ink usage will not be a major expense so don't worry.. you'll need to replace carts every so often but just remember that if you don't print very often, you might clog up your printer and then use tons of ink to keep clean the heads. So, try to print something at least twice a week.. you'll save ink that way.

Oh... and try to keep the printer on all the time... that way, it won't go through the head clean when you turn it on... another huge ink saver! Good Luck!
