Problems with HP Printer 940C

Hi, It's been a while, but I'm back - with a probem, of course.

My current computer is an HP Envy 17-in Lapytop, with Windows 7 Home Premium, 64 Bit

My printer is an old HP Deskjet 940 C

My Problem: I am unable to print wit this, tho I could in the past. Under "Control Panel", it shows my printer as HP deskjet 940 C. then it shows "Printer Offline"

So, How do I get it "Online" so I can print again?

 

"Offline" simply means the computer cannot communicate with the printer.

How is it connected?

If it's directly connected (ie: USB cable), you may need to uninstall the HP software/drivers, reboot, and then perform a fresh install.

 

Is the printer connected directly to the laptop, or to another computer or to a router?

 

I have a second HP 940C printer with a problem. When I hook it up and turn it on, the orange light at the left starts blinking. Then, when I open the lid, the printer heads move to the left and stops on a frown-faced indicator. The printer is then unable to respond to any print commands.

On Devices and Printers, I tried to print a test page. Of course, with the printer still flashing its light, nothing happens.

How do I get the printer head away from the blinking status to the smiley face on the right side?
