HP 656c reinstall drivers message
After many months of no printing problems, I received the
message "A required HP file is missing or corrupted. Reinstall HP driver software". After receiving the error message, I follow the procedures, exactly, to uninstall and reinstall the drivers. The printer, then works fine until I restart the system. I then get the message again. I have tried everthing I can think of including a complete scan disk. I even replaced the disk drive with a new one. I completely uninstalled my anti-virus software. I must have tried this at least 30 times. I have tried to install the drivers from my original CD and I have tried using the newest downloaded drivers. Every time, without exception, the printer works fine after the installation of the driver software, then fails after the restart. |

This article may help. It has lots of good troubleshooting tips.
HOW TO: Troubleshoot Printing Problems in Windows 95, Windows 98, and Windows Millennium Edition http://support.microsoft.com/?kbid=128345 When you got a new disk drive, did you install things from scratch or did you restore a backup? If you installed from scratch, did you install the operating system, then the printer and test? Did it work? At what point did it fail when you reinstalled your programs? Clean booting will often help you determine if something loading at startup is causing your problem.

Here is the additional information you asked for and some
that you didn't. I copied the C: drive that I replaced using the MaxBlaster software that came with the new drive. I thought the problem was caused by the IDE drive not posting the data from its hardware buffer to the actual disk. Thus the information would disappear when the system is shut down. The results were identical with the old and the new disk. Specifically: When I try to print from any application (not when I install the drivers), I get the message saying that a file required for printing is missing or corrupted and that I need to reinstall my dirvers. I then reinstall my dirvers (exactly according to HP's procedure), and the printer works fine. Until I do a restart, at which time the problem occurs all over again. Last night I did some more expirimenting. I discovered the exact file that somehow gets deleted. It is windows/system/hpzpcl07.dll. The file is present after the dirvers are installed and the printer works fine. After any system restart (or shutdown) the file is gone and my problem re-occurs. This is not intermittent, it happens every time. If I copy a saved copy of the file back to windows/system, the printer will, once again, work fine. But the file will, once again, disappear on the next restart. Why would just this one file get deleted every time that I restart my system? My printer was working for months before this started to happen. It makes no sense!! -----Original Message----- This article may help. It has lots of good troubleshooting tips.

Well, I solved the problem myself thanks in part
to "PattL"'s advice. I had also been trying to get a solution from HP on this. Here is an excert from my last replay to HP: Dear HP, I resolved the problem myself but the cause should be of interest to you. Others may encounter this and the problem was made worse by directions in your help file. The problem was cased by a Trojan back door that was placed in to my "Run" registry entry. The program (C:\windows\aqadcup.exe) deletes your file hpzpcl07.dll every time the system starts up. "Why" you ask. Because when a user tries to print and this file is missing, your software displays a message telling him to reinstall the HP drivers. In that message is a link to instructions. In those instructions, you specifically tell the user that he should remove any anti virus software before the uninstall/reinstall of your drivers. (Which I have found to be not necessary). After the uninstall, the system must reboot, without the virus protection. Aqadcup.exe then runs again at start up, only this time virus protection is gone and the program proceeds to do more damage (including deleting regedit.exe. It also did something to my Norton Anti Virus that required me to reinstall Norton Anti Virus). I believe the reason that this virus targeted your (HP's) file is because your instructions specifically and erroneously tell the user that he needs to remove virus protection. I think you should change your instructions to say that removing the anti virus protection may be a possible cause for a failed installation and should be attempted after the uninstall (which involves a system restart) but before the install (which does not involve a restart). Also you can add this situation to your database so you can help others better than you helped me. I can't believe that I am the only person in the world that this has happened to.

Wow! Great information. Thanks for reporting back!
