Check in the system preferences in Printer/Fax If your HP device is Combo Printer Scan you might have to change to Scanner first.

See this: https://skitch.com/pjonescet/8mj2e/print-and-fax-32-bit 

Switch to scan first and set up as necessary. the quit or hide Printer Fax

Now see if the scanner show up in Acrobat.

Did you click on the link provided in my answer. The way HP Printer scanners are setup you can use one or the other but not both at the same time.

Switch to scan in Printer/Fax. Then go back acrobat choose PDF from Scanner.  the scanner should then show up or you can select it.  Then you can use the the scanner. To print you have to go back and switch back to the printer.

Both don't work at the same time.

Okay your is setup similar to mine.

Click on the scan Tab.

Setup as necessary (If necessary)

Now quit Printer/Fax (leaving it with Scan Tab activated).

Now go to acrobat and create PDF from Scan : http://www.screencast.com/t/WGSYIjJWOEd3

Next as shown here: http://screencast.com/t/QqDXVA6qXpXM click on button as shown and slect your scanner.

You can now make a scan.

This is ridiculous.  I just "upgraded" to an HP scanner from a Brother and I find myself having a more difficult time with Acrobat.  How is it possible that Adobe does not support HP scanners?  I have tried everything here and none of it seems to work.

I am having the same problem with my HP 7515.  Adobe X with iMac.  Won't recognize the scanner.

Adobe say it's up to HP to support their own scanners and that it's not an Adobe issue.

Depending on your printer and the type of driver update, you might need to scan in a different way than you did before you installed Mountain Lion.

 

 

NOTE:Scanning to the computer from the printer control panel is not available when you scan with Preview, Image Capture, or Printer browser methods. You must use HP Scan software to scan from the printer.

Unfortunately, Coach, seems like you will need to do the (silly) steps that I do by scanning in with Preview first, then open the particular file with Acrobat. Annoys the crap out of me! One would think it more streamlined to go 'Create' >> 'PDF from Scanner' >> Choose scanner ... from within Acrobat.

Hmmm ....

So today, January 18, 2013, OSX 10.8.2 has released the newest HP Drivers, and still this problem persists. I decided to cal HP, and will save you all the long conversation, because it all comes down to this one thing: According to HP, if the printer prints, and it scans using THEIR scan utility, then the hardware works as it was intended and their is no problem. They basically said, and hung up on me when I asked for clarification, that HP designs its products to work with its software and could care less if it doesn't work with another companies software.

The ball, as they say, is now in Adobe's court as to wheather they will attemp to please their consumers and make this work, or if we as consumers need to buy something other than HP FROM NOW ON.

I, for one, have been scanning directly into Adobe products since 1993, and am very discouraged that I am now being prevented from doing so.

Mac OSX 10.8.2

HP OfficeJet 6500A Plus (which may be available at my next garage sale!)

Today I purchased Acrobat XI and after spending an hour or so trying to configure the HP D110 as a scanner, finally ran onto this thread.  I'll use the HP app to scan and hope that Adobe or HP finds a solution.
