I got hit by something.

What did you get hit by and who removed the infected files?

Generic Host Process for Win32 services has stopped.

That can be related to virus, malware problem.

"I'm sick and tired of this and I'm not going to take it anymore!"

Sorry for lack of detail. I'm going off the deep end and now at the point that I sometimes don't read what MalwareBytes has found - I just get rid of them. Rogue this, trojan that, yeah,yeah, yeah....frankly I'm so sick of all this b.s. Four computer users in the house and I'm the one that has to figure out this "shtuff" all the time instead of being productive myself.

Now, back to our featured story: I also just installed a wireless repeater last night. I am wondering if some kind of router setting got changed. I have since deleted the printer from the router table and let it find it again, still no luck. Everybody can see the printer, sitting "idle" but nobody can print to the damned thing. (BTW, HP all in one desk-jet printers are a pita, no matter what the reviews say. Using them as scanners is another test of one's mental balance.)

I might use this episode as an excuse to upgrade the XP computer, but I'd hate to find out the problem is elsewhere on the network.

you can always view your malwarebyte logs to see what was found and removed, open malwarebytes and look at the tabs there is a logs tab.

If it were me to make certain that the infection was actually fully removed which it really sounds like it was not I would go to this malware removal forum, register and post a thread there in that area asking to help check if it is all clean. Once you have their say that you are clean then you know that remnants of the infection are not what is causing the problem but till then anything you do may not work because of those remnants.
go here start a thread in that area and explain what has happened what was found and what you have done etc as you did here,in fact link back to this thread. If you need help doing that just let me know.
Analysis and Malware Removal

Until you investigate what's causing this error Generic Host Process for Win32 services has stopped, etc. You're not going to get those printers working.(I'd follow Raven's advice) There use to be a hot fix(kb84391) for this with service pack 2. Speaking of that you need to be at Service pack 3 now. HP printer drivers can also cause this.

1 Thing you might consider is to:
Disable your firewall and see if the printer works.

You really need to follow up on raven's link though

One other truly interesting thing I found on the error Generic Host Process for Win32 services has stopped.

There is an automated fix for it, but when run it disables Network printing! How crazy is that.

It turns out I do have XP with service pack 3. (sorry).

Regardless of whether it was a virus or not, I think the network settings got changed, so I need to work on that first. (Everybody's flipping out that the printer/scanner isn't available). Switching or adding another antivirus / anti-malware product might be in order also. (I use AVG (free version), MalwareBytes, CCleaner). I might bite the bullet and purchase Kaspersky next.

Access Denied" Error Message When You Print to a Network Printer or View the Printer Properties

Here is a link that might be useful: Access Denied error

please do yourself a huge favor and just visit the help forum we mentioned. Infections change all kinds of things on the pc which until the full removal occurs will be fruitless to try to fix. Plus you may find the info there you need for the problems you are having.
You still have not answered the first question asked, what was the infection, all you need do is look in the malwarebytes log. With out answers to our questions how can we proceed, guessing is a waste of everyones time.

RC, Point taken, thanks. When I get back on that computer I'll get that info.

Zep, Thanks.

BTW, a bit more info "on access denied". On another networked computer (Vista), while it does see the printer, it cannot search for other printers on the network. Message is "Active Directory Domain Service" is not available. I think that on the XP computer, it is blocked similarly, with a similar message "Directory service" unavailable.

Thanks for your help. I have to attend to other matters at the moment. I'll bet back to this stuff later this evening hopefully.

Read the posts regarding the inability to print. I have nothing to add as all the suggestions appear to be along the proper lines of diagnostics and resolution.

I also read your comment about the HP AIO printer itself. May I suggest after your printing concern is resolved you visit the HP site dedicated to your AIO, and look for updated software; specifically a patch. HP released a scanning patch along with upgraded software over the summer for some AIOs. Perhaps yours was one and something will resolve your frustration with the unit.

DA

HP officejet J6480 network printer finally up and running again. Turns out it developed a network conflict when I installed the wireless repeater. But that was only the beginning of the fiasco. I wanted to update the firmware and reinstall all the software since I had a couple minor glitches over time. That's when I learned (the hard way) that sometimes one cannot uninstall HP software, and then reinstall it. Look up "Error code 2753" and you will see what folks go through. HP was not helpful for solving it, but I found a working solution from a visitor in their forums (yes, renaming a couple files in the system files did the trick - since they cannot be easily deleted).

This may be helpful to others with a similar HP nightmare, so here is the thread:
