Why, oh why does the ink cartridges run out so fast? An even bigger question is – why do you change one cartridge (the colored one); then half way through your printing project, the other one runs out??? AND you only bought the colored cartridge on your first run to Wal-Mart thinking you had lots of ink left in the other one. Now, you have to load your lazy butt back into the car and head across town. JUST so you can get your Christmas letter out!!!
