Unable to print or scan from my computer to HP Officejet j5780 All-in-One printer

[JHM10]

I am unable to print and scan. 

Print jobs get stuck in the spooler.  I went to services and stopped the spooler, shutdown and unplugged the printer and computer, came back a couple of hours later and plugged both back in and restarted them.  No Change.

When using the HP Solution Center I press scan and nothing happens.   In the scan properties menu it reads that there are no events for when the scan button is pushed and it does not give me the option to change this. 

I ran the HP Print and Scan Doctor.  It read that the printer is fine and a test page printed.  Regarding scan it read that everything is fine except for the HP Solution Center test.  It reads that the full software is needed to provide a solution. 

I have downloaded the full software solution and installed it.  The computer shows that all parts of the software is installed.  For good measure I uninstalled the software and reinstalled it.  I still have the same issues and the HP Print and Scan Doctor still says that it needs the full software or update.

On the printer's front panel under "error messages" it reads that computer is not connected.  My computer, however, shows that it is connected.  The computer can find the device to run diagnostics and is able to run the scanner to test it.  The HP Solution Center shows the printer is connected.

Any other ideas on how I may be able to print and scan again?
