I deleted and re-added several times. I geives error message USB malfuntion. I have a cable modem with phone network. I can get the printer assigned in there but it will not print from any any device. I did a reset on the printer  and restored factory defaults re-entered all info several times and get the same result. the fax - scanner - and copy  all work properly manually but will not  take commands from my competer either wired or wirelessly.

Hey @orville1, 

Welcome to the HP Support Forum. :robothappy:

I see that you're unable to print, scan or fax via Mac using your HP Officejet 6500A Plus e-All-in-One Printer. I would like to help. 

Have you tried plugging the printer into a different usb port on your Mac? If not, try all available usb ports to see if you get a different result. If you haven't been using the usb connection disregard this tip.

Try the following steps in sequence:  

1. Uninstall your printer - click here for instructions.  
2. Repair disk permissions on your Mac - click here for instructions.  
3. Once you've finished running the above-noted utility, restart your computer. 
4. Lastly, click here to reinstall your printer.

Please let me know the result of your troubleshooting by responding to this post. If I have helped you resolve the issue, feel free to give me a virtual high-five by clicking the 'Thumbs Up' icon below and clicking to accept this solution.
