I have an HP laserjet P1600dn operating on a hp touchsmart520 using Window 7 {64 bit}. The printer was on-line when I went to bed last night; it's now offline and will not come back on line.
First thing I tried was to change the USB port. No success. Then I changed the usb cable. No success, I took the power plug out, waited 30 seconds then plugged it back in. Nothing. After every step I restarted the computer.
I'm at a loss. Does anyone have any other ideas?
