I'm using a Mac and have software up to date. I have reinstalled my HP Photosmart C4780 (4700 series driver) software.
The printer will print the first job, but when I try to print another one it says "printer is busy". If I try to shut down the printer it seems to be unable to shut down. When I unplug the printer and restart it then it will print the next job.
I also get a message that my computer has components installed that are not compatible with my printer, but I have not installed new components. All wireless networking is performing correctly. I can't find anything wrong in diagnostics.
It's like the printer does not recognize it has completed the job. Does anybody have a clue?
