Mac printer purgatory brought to you by HP …

with 3 comments

If you’ve ever run into this error trying to install an HP Printer on a Mac, let me tell you how to fix it:

Some of the software for the printer is missing.

There’s actually a discussion on Apple’s forum without an answer. The answer is beware of HP Printer downloads. Not all are compatible with the current Leopard (10.5.x). A number are only current for Tiger (10.4.x). If you download them and install them, you should consider using a time machine recovery of the Operating System.

If you haven’t installed them, don’t do it until you back up the /Library/printers/hp directory (typically about ~650 MB). It will enable you to recover without a full backup of the operating system. Open a terminal and run the following command:

# mv hp hpbackup

If the HP drivers apply and things don’t work you can recover. You can simply do the following two command from a terminal session:

# rm -r hp
# mv hpbackup hp

If the HP drivers apply and things work you’re fine. You can delete the backup directory and its contents by using the following command in a terminal session:

# rm -r hpbackup

  1. I am getting this error when trying to re-add my HP Deskjet D4160. I have a time capsule and tried to find the file that you specify but I cannot seem to find it. I really need to get my printer set up for school but I cannot seem to solve the problem. I have the disk that my printer came with and I tried to re-install the software but I continue to et the same error. Any suggestions. What would be the step by step instructions to solve this.

  2. It wants to know how backing up first is a solution to this error message when you encounter it. Unless you are saying the only solution is to reinstall your whole operating system… Which again, sanity wants to talk to you about.

  3. Typically, it’s a corrupted file, and recovering the OS is the only option.
