How to fix this printer problem?
well, I have a Dell Photo Printer 720 and I have a computer with Windows XP. the problem is that when it came to print one of my important documents, the printer will not print. I was not even on! So when I manually turned on, made a sound as if rolling on paper. But it was still printing! Then came a message and said: "Communication not available the printer can not communicate with the computer Try these Solutions: .. Disconnect and reconnect the printer cable to disconnect or reconnect the USB. cable. -Restart your computer. "I tried all those things but does not work. What I can do? The paper is due tomorrow!
Try reinstalling the drivers from the CD that comes with the printer.
