打印机突然不能共享他人的

My printer suddenly can't share with others anymore. When I tried to print a 700-word document, it just stopped halfway through and I couldn't get it to print no matter what I did. I checked to see if it was out of ink but there was plenty left. I tried restarting the printer, but it still wouldn't work. I even tried restarting my computer, but nothing seemed to work. I'm really at a loss as to what could be wrong.
