HP All-in-one printers disappearing when there are changes in the network status
I am facing some issue with HP printer on my network. I had never face this issue before. But somehow it looks the printer fails to work on the network. The printer model is Photosmart C6180. It is connected on the network. There are 4 workstations on the network among which one is on Windows XP and other 3 are on 64bit version of Windows Vista. the XP system does not has any problem with the printer while in Vista the printer sometime appear and sometime it does not. It is very annoying. I have to enable and disable the network adapter and then after a few time it is visible.
HPSCV32.DLL and HPSVC64.DLL
I think it is simply a waste of time to struggle on Windows Vista. Sometime the drivers fails and sometime the problem lies with Vista interface. While the same on Windows XP work like charm. There is no problem at all. The issue lies with TCP/IP stack bug in Vista due to which your printer keeps on disappearing. So in short it is a OS bug. You can try to update the system files and run windows update. I hope Microsoft is having some kind of hotfix available for the same that can provide support to deal with the issue.
HP tech support response all-in-one on network
I am facing exactly the same with a HP scanner. The scanner is connected to my single computer. The scanner works fine but sometime it is not available. I have to add it manually a number of time. It looks Windows Vista is not capable of remembering the settings due to which this kind of problem appears. I had downloaded the Vista version of hardware from hp site and the problem is still the same. I am sure there will be some way to fix the problem. Any updates on it is much helpful.

I have had the same problem with A Dell Latitude E6500 running Vista and an HP 6310 All in one, having to re-install the printer software again and again. I've tried all the solutions suggested here and nothing keeps the printer from disappearing. Nothing works, of course-neither HPs' nor Microsofts' fault...I'm basically screwed until I can afford a new printer, and it sure as hell won't be an HP.
