Printer Unavailable HP Officejet 6600

[Yosoydame]

I Needed to scan an important document to my computer.  I directly connected the printer to my computer and went to the HP Smart app.  It said the printer was unavailable.  So I reinstalled HP Smart and Disconnected the printer from my computer.  Shut it off for a few minutes with the power chord off and reset it.  Still nothing.  I don't know why It showed the printer was unavailable so I decided to do a dumb thing and print a test page from my computer.  Bam it printed.  So your software is really buggy because the 2 are obviously connected.

I found a fix by searching for a 3rd party WINDOWS scanner app.  I used that and it immediately scanned.  HP Smart is Trash.  That's all I created an account on here to say.
