DeskJet840C
Microsoft Windows XP

It worked fine last week when I had Charter (Spectrum).  Now I have AT&T. Everytime I try to print on my DeskJet840C it just blinks on the third one from the top.

The top one is the power button

the next is the one you hit to feed the paper into

and the third one is the one that blinks if you are out of ink.   I have ink!

Maybe its a driver or something. I have even pulled out the cord in the back of the printer for 45 sec.  I have also restarted the computer twice.  How do I put a driver on?

As soon as I hit print....it starts blinking.  

Yes....it worked fine last week.
