I've searched the forum for similar topics, but did not find any. Sorry if I missed any.

I had several printers installed, and was trying to install an unsupported printer (HP Color Laserjet 1600) by installing the HP driver packaged for the 2600n. It didn't work, but it deleted a few of my printers (HP and Epson).

I went to time machine, and restored my printers folder, but this did not work.

Is there some other way to restore this or to uninstall the HP software that I should not have installed?

thanks.

    Hi MacRussell,

     

    I had a similar problem - I made a huge mistake yesterday by going into System Preferences, left-clicking on the printer I wanted to connect to, and clicking on the "Reset Printing System" which led to a box that said "Are you sure you want to reset all of your existing printer queues and all pending print jobs?" and then I clicked OK. I thought it would cancel any open print jobs (and there were none open) and reset the printer that I was trying to connect to. What the prompt SHOULD have said is "DO YOU REALLY WANT TO DELETE ALL OF YOUR PRINTERS???" Because that is exactly what happened. I searched for a very long time on these discussion boards and on the rest of the Internet for a way to get back all of my installed printers. Why not just reinstall them? Because I had way too many network printers, local printers, etc. and all with their own customized settings that I couldn't remember. But I finally found the answer, and I hope you don't mind me posting it as an answer to your question, but when I found your post I was upset that no one responded because I also really needed to know what to do. But I did fix it, everything is back to normal, so this is for all those folks out there that are in the same situation we were in.

     

    Here's what I did:

     

    Step 1: Open Finder, go to Macintosh HD > Users > (YourName) > Library > Printers. That folder should be empty since you deleted those files when you reset the printers. Leave that folder open. Open another Finder window and go to your Time Machine backup. For me, the path was TimeMachine > Backups.backupdb > (2011-05-19-034706 - use your latest backup date, this is just the date of my last backup) > Macintosh HD > Users > (YourName) > Library > Printers. That folder should have some files that have your printer name.app (i.e. hp officejet 5500 series.app). Copy all of those files , and paste them into the Printers folder on the first Finder window we opened above. Now, close both those Finder windows.

     

    Step 2: This is a bit tricky, as we now need the Mac to show us some hidden files, copy those files, and then hide those files again when we are done. Do exactly as follows to avoid any problems:

     

    Open the Application Terminal (in the Utilities subfolder)

    At the prompt, type these two commands (hit enter after each command)

     

    defaults write com.apple.finder AppleShowAllFiles TRUE
    killall Finder

     

    Now, hit Command-N to open a new Finder window (or just open it from your dock). Click on your Macintosh HD under Devices, then you will see a bunch of folders that are normally hidden. You want to go to the etc folder by double-clicking it. Then, expand the cups folder and you will see the ppd folder. On your Hard Drive, it will be empty since you deleted those files when you reset your printers. So here's the path in case I confused you: Macintosh HD > etc > cups > ppd. Now, open another Finder window and go to the same path on your Time Machine backup. For me, it was TimeMachine > Backups.backupdb > 2011-05-19-034706 > Macintosh HD > etc > cups > ppd. You will see that folder should have some files that have your printer name.ppd (i.e. hp officejet 5500 series.ppd). Copy all of those files , and paste them into the empty ppd folder on the Finder window on your hard drive. You will be asked if your sure and to type your password, so just go ahead. It will be okay.

     

    Step 3: We are not done yet. There are some files in the cups folder that we also need to copy from the Time Machine backup into your hard drive. So keeping both those Finder windows open, go up one level to the cups folder (on your hard drive, Macintosh HD > etc > cups ; on your Time Machine backup, TimeMachine > Backups.backupdb > 2011-05-19-034706 > Macintosh HD > etc > cups. Copy the following files from your Time Machine backup to the hard drive:

     

    cupsd.conf

    cupsd.conf.bak

    printers.conf

    printers.conf.O

     

    Now, there was a file on my hard drive in the cups folder that was not in my time machine backup called cupsd.conf.O that I didn't know what to do with, but I figured it couldn't be good. So I copied it into a temporary folder (just in case) and then deleted it from the cups folder on my hard drive.

     

    Step 4: You are almost done. Go to System Preferences and click on Print & Fax, and you should now see all your printers back in the list. Congratulations, your printers have been restored! But we still need to hide all those pesty hidden files and folders in Finder, so close all open windows and go back to the Terminal application and type the following commands (hit enter after each command):

     

    defaults write com.apple.finder AppleShowAllFiles FALSE

    killall Finder

     

    Then close your Terminal application and open a new Finder window and it will be back to normal with no hidden files or folders showing.

     

    You now have your printers back to where they were before you hit the same "Reset Printers" button that I did (in error) and took me 2 hours of research to figure out how to undue the damage, or had some printers deleted in error when installing an unsupported printer.

     

    If for any reason this doesn't work for you, all I can say is that it worked for me and I wanted to share the fruits of my labor with others who are in a similar predicament as I was. I am by no means an expert in this area, so although I don't see any reason why it wouldn't work, you just never know how one persons computer differs from another, so I apologize if it doesn't work out for you. But I really think it will, so good luck and happy printing!

    Paul,

     

    Thank you! Thank you! Your instructions were perfect, as I made the same error: i.e. hit "reset," which lost all my network printer settings.

     

    After following your suggestions, my settings are back and printing is restored. Good job. I'm grateful you took the time to post your fix.

    Glad to be of help. And I'm really glad to see that it worked for someone else, not just me.

     

    I really think that Apple should change that message to "DO YOU REALLY WANT TO DELETE ALL OF YOUR PRINTERS???" so none of us would have to go through this in the first place.

     

    Thanks for letting me know that it worked for you too!

    I fully agree that the warning message should be explicit. I recall that I highlighted just one printer entry, (which was only used temporarily when I was out of town.) So, I simply thought I was deleting that one from my printer options, since I didn't need it there any longer. When all the printers disappeared instead, I had this awful sinking feeling, but thought surely there was a quick way (single key stroke) to restore them.

     

    I also recalled the hours it took to install a network printing option (HP printer) at home when my Macbook Pro was newly purchased a couple of years ago. At that time the tech support guy who helped me on the phone seemed nearly as clueless as I was, and we tried so many configurations before something finally worked. I had even stopped taking notes, because we went through so many trials. I think it took literally 3 hours on the phone with him. The dreaded prospect of going through that again was playing through my mind last night when I lost those settings.

     

    I found a number of less helpful threads before seeing your step-by-step fix. I also had not needed to use Time Machine for restoring prior to this. Just glad I had it!

     

    This does seem like an area (printer settings AND network printer setup) where Apple could use some improvement in regard to user friendliness.

    Thank you so very much for your specific instructions.  I wished others would learn from such, instead of merely redirecting you another unhelpful post.  The problem experienced here is a very understandably common one.

    Thank you very much Paul. I also deleted all my printers by mistake and I was able to restore them using your step-by-step instructions.

    Thanks so much for posting this, Paul.  This saved me some agony as well, particularly as I use printers at various clients' offices, so I was spared having to fiddle around getting my MacBook back in sync with their printers.

    Unbelievable!  This is just another in a PLETHORA of reasons why I'm really starting to despise my Mac computer (I adore all of my other Apple products, but the computer I want to throw out the window).

     

    I thought the same as the other people - that I was deleting print jobs.  It wasn't working for me to delete them in the que, so I tried that.  How ignorant is it to not make that statement more clear?  I can't be wrong when so many people read it the exact same way I did.

     

    My problem is, I can't seem to find my backups so now I have no clue what to do.  This is just ridiculous and I don't have time for it.

    On a 10.6 box with all printers gone, I just restored all 8 printers in about 20 seconds without TimeMachine like so:

     

    Utilities -> Terminal.  In the terminal paste in, one at a time, each of the one-line commands in bold below.

     

    • Stop the CUPS daemon with the following command:

    sudo launchctl stop org.cups.cupsd

     

    • Assuming printers.conf.O is bigger, ovewrite the empty printers.conf with it:

    sudo   cp   -p   /etc/cups/printers.conf.O   /etc/cups/printers.conf

     

    • Optionally (I did not need to do this myself) restore cupsd.conf from the O (older) one:

    sudo   cp   -p   /etc/cups/cupsd.conf.O   /etc/cups/cupsd.conf

     

    • Restart the stopped CUPS daemon with the following command:

    sudo launchctl start org.cups.cupsd

     

    YMMV, but you might want to try above commands before all the overly complex machinations above and at https://discussions.apple.com/message/9568833#9568833

     

    And I agree that with the need for a clear warning "Do you *REALLY* want to delete *ALL* your printers?" That is not clear to most folks. Even detailed info at http://support.apple.com/kb/HT1341 bluntly speaks of deleting queues and jobs, with nary a mention of printers!

    MacRussell... DUDE!!! You saved me!

     

    Thank You, thank you, thank you... for writing such detailed instructions.

     

    You have no idea how much grief you saved me... just wished I found this article about 24 hours sooner.

     

    Someone needs to buy this man a beer, oops I mean a refreshing beverage of his choosing!

     

    FYI, you trick still works with OSX 10.7.3

    I didn't have the following file on any of my Time Machine back-ups:

     

    - cupsd.conf.bak

     

    For the rest I followed all of your instructions Paul, but I didn't get my printers restored

     

    I have a Macbook Pro with 10.6.8 on it.

     

    Tips, anyone?
