Enable Scan to Computer - Communication Error

[Phippster]

I have the same problem.  I'm using the very latest software with the Lion 10.7 specific upgrade from HP.  It works for the first 24 or so hours, but after that I must restart my Mac in order for it to work.  Extremely frustrating.  I want to take my OfficeJet 8600 back.  HP support is kind and nice but clueless and can't solve it.  The other day I asked about adding additional scan tasks and the gentelman from HP told me to disable my firewall.  Uhmm...huh...not even remotely related to creating additional applescript workflows?   This seems to be a major issue for HP and these printers.  It's unresolved and many people with Lion are experiencing it.  Please HP get a real engineer to look at this problem!

In the System Log the following is present:  HP Device Monitor: dnssd_clientstub read_all(10) failed 0/28 0

Editing a post I just put up an hour ago.

Ok, I really tried hard to figure this out when I bought our new printer a couple months ago.  I had installed all the latest drivers from the website and then I was ticked because my husband's new computer, which he didn't download drivers from the site, showed up on the printer as a computer I could scan to.  Well, I decided to go check out the website again for updates and even though my mac automatically downloaded some update from hp a while ago, I figured maybe it didn't give me the ones I needed.  So I downloaded the latest drivers and the update that said it was specifically targeted for this problem (I have the officejet 6500A Plus). But it wouldn't let me download the fix for the scan to computer problem.

So I figured out what the problem was.  You know when you install the drivers and you have the option to uncheck installing the optional recommended programs and crap?  It's supposed to be nonessential stuff.... Well, I had unchecked those.  When I went back and checked them (I did both- I didn't want to fuss with this anymore so covered all the bases).  THEN I was able to download the last update for this mac scan to computer problem.  And now I can use the scanner properly.  This should have been part of the essentials, though.  I really resent this way of doing business.  HP knows they are putting out a product that isn't completely ready just so they can get it out before the competition.  And that many of us will spend hours troubleshooting and waiting for updates.  Never buyhing an HP printer again.

I finally got miine figured out.  don't know if you have the same printer and if they've done updates for yours, but my officejet 6500A Plus was fixed thusly:

Download the latest driver updates from the site (even if you already did so), but make SURE you check those boxes for the optional crapware to make it "fully functional".  No, this shouldn't be necessary, but I want my scanner functional.

Now see if there is also an update specific to this problem. For my AIO, there was.  Download and install that.  I restarted both devices for good measure.  Now I can scan to my macbook pro.  Good luck.

Well I finally gave up thinking the problem with not being able to scan to computer was something to do with Wireless/Wired connectivity and Bonjour.  So I moved the 8600 next to my computer and plugged it in via USB.  Computer to scan worked (just like it did via wireless) for about 12 hours.  Today I go to use it and no success. The printer says "preparing to scan..." for a long time, no processes open on my Mac (normally a little dialog window with progress bar opens up) and eventually the printer gives and error message that the scan was unsucessful because it couldn't communicate with the computer.

So with all the variations I now know the following ARE NOT responsible for the error:

- Wireless vs. Wired connection

- Router settings

- WAN Firewall settings (why HP would ever recommend turning off the WAN firewall to print to a USB printer is beyond me anyway, but hey I gave it a try

- USB vs. internet connection

The clear culprit is the HP software that listens for the connections on the Mac.  There's a problem with that!  I'm a very technical guy familiar with logs, networks, etc.  Could HP please have a real engineer give me some support.  I'm about 24 hours away from taking this back!

Exactly the same problem as the previous post is being experienced here.  The software fix that supposedly addresses this issue does not work.  I have reinstalled the full HP software many times only to have the scan to computer functionality work temporarily before crapping out again.

HP need to respond to this error ASAP or I will be returning my HP Officejet 6500 Plus printer.
