ApplicationsIf you have installed the HP printing software, you should remove it. It's not needed with that printer.

Hope this helps.

Jul 21, 2014 8:31 AMby Steven Fisher1,I got excited cause I thought it was fixed! But nope. I used Clean My Mac to remove all the HP software. Then I reset the print service and restarted the mac (did this for both).
On the macbook pro the 7510 showed up as a nearby printer. So I installed it, everything went automatic, and it worked. a few hours later it stopped working!
On the macbook air, it did not show up as a nearby printer but rather as a bonjour printer on the add printer dialoge box. I went ahead and clicked add and interestingly it added the printer using the AirPrint driver. On my Pro in installed using the HP Driver.
Can confirm the printer is connected to same network. Can print to it via USB from both macs, via wifi from iOS devices, and wifi from a windows laptop.
Maddening! Any help is appreciated.
TIA

Applications
"CleanMyMac" is a scam. It may have wrecked your whole installation.
The developer's instructions don't completely remove it. Follow those instructions, then do as below.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
/Library/LaunchDaemons/com.macpaw.CleanMyMac2.Agent.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Repeat with this line:
/Library/PrivilegedHelperTools/com.macpaw.CleanMyMac2.Agent
Restart the computer and empty the Trash. Never again install "CleanMyMac" or anything like it.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
Reinstall the OS.* Your data should be unaffected unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.

Jul 21, 2014 12:48 PMby Steven Fisher1,HelpfulOK I don't want to jinx anything but a simple restart of my Airport may have fixed the problem! I was running down the list of solutions in my head and I realized I had pretty much restarted every device except the Airport. Restarted the Airport and now the printer has worked since. Odd thing is that I have the FiOS router handing out DHCP and the Airport is in bridge mode. So far so good. I will keep you posted. TIA for all the tips.
