    Error message: "An error occurred while trying to add the selected printer. Error:-50."

    When trying to re-install my printer (HP LaserJet 1320) to my computer (Mac OS X, version Tiger 10.4.10)
    I receive the above error message, which prevents the re-installation of the printer. The printer is directly connected to the computer via usb and there is no network involved.

    Here is the scenario:

    From the Printer browser window I select the printer type (HP LaserJet 1320) from the Print Using drop-down menu, after which the above error message appears and ends the printer installation process.

    Does anyone have any information on the Error 50 error message and how to overcome it?

    Thanks for any tips.

    Start by repairing permissions (Disk Utility) - all HP installers (OK - many) screw up permissions.

    Here are the results. Looks to be okay.

    Verifying volume “HP LaserJet v5.5.2.051”
    Checking HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking Catalog hierarchy.
    Checking volume bitmap.
    Checking volume information.
    The volume HP LaserJet v5.5.2.051 appears to be OK.

    1 HFS volume checked
    Volume passed verification

    Here are some more generic things to try -
    Reset Printing System (new in Tiger) - In Printer Setup, click this menu item found just above Quit Printer Setup.
    Download the Combination Updater from Apple, use it to re-Update OS X.
    Try Printer Setup Repair from www.fixamac.net.
    Put in your install DVD and restart while holding the c key. DO NOT continue the installer - instead, find Disk Utility in the top (Finder) menus and use it to repair the hard drive.

    One more - delete the HP folder from Library/Printers, then reinstall the HP driver (get latest download).

    How do you access the Combination Updater after installation?

    Hi gsahli

    Thanks for all the great printer diagnostic checking ideas.

    For now I have a question about the Combination Updater from Apple.
    I downloaded and installed this software, but I expected to see a new window interface
    icon after installation. But there is nothing like that.

    Does this update software simply update the "Software Update..." option found within the
    Apple pull-down menu? In which case, the Combination Updater would be accessed via
    this same "Software Update..." option. That's my guess.

    Thanks for any clarification.

    Combo Updaters are available only via download, not through Software Update. The Combo updater includes all changed files since the original 10.4 came out (and security fixes before the Combo came out).
    I'm not sure about what you expected to see....?

    Trying to install a network printer by using Printer Setup Utility the error log file shows the following:

    LoadAllPrinters: Unable to open /private/etc/cups/printers.conf - No such file or directory
    E [25/Oct/2007:19:54:40 +0200] LoadAllClasses: Unable to open /private/etc/cups/classes.conf - No such file or directory

    I lost the two files. Can anyone provide the files for Standard Tiger OS X 10.4 and a PowerBook G4?
    Or how can I reinstall the complete Application for printing.

    I am new in the forum and did not find out yet how to post a new message.

    Thank you for any help.

    Combination Updater based on Automatic Updates

    Re: I'm not sure about what you expected to see....?

    Well..., okay. I've downloaded and installed the Combination Updater from Apple.
    So that's it then. No further input needed from me.
    That must mean updates are automatic without user input needed.

    Hi schwine - yes, if you installed (regular Mac installer window), that all that's needed.

    But are you printing yet?

    For macg4user:
    Start a new topic by clicking on the button New Thread. You need to tell us more info, like printer model and what you've tried so far. classes.conf isn't needed, printers.conf is regenerated by restarting the Mac (I think). So those two errors aren't any help.

    Looking into replacing missing printing files

    But are you printing yet?

    Not yet. I've gone through all of your excellent suggestions for printer diagnostic checks, and the only one that has been helpful or provided more information is the Printer Setup Repair software tool. It has identified that 11 printer files are missing from the hard drive. So now I will attempt to look for these files on my Mac install disk and try to install them individually using the Pacifist software tool. I hope to have this done by Monday.

    One one hand, the results say that "Printer Setup Repair cannot replace these (missing) items," but on the other hand it states that "No problems were found." Maybe it means no problems other than the 11 missing files. In any case, I'll see if I can find and re-install these files in the coming days.

    Meanwhile, here are the results from the Printer Setup Repair tool.

    Starting permission verification and repair, omitting localized files...

    The file /private/etc/cups/classes.conf is missing. This file is deleted when using the Reset Printing System option.

    The directory /usr/include is missing!
    The directory /usr/include/cups is missing!
    The file /usr/include/cups/cups.h is missing!
    The file /usr/include/cups/http.h is missing!
    The file /usr/include/cups/image.h is missing!
    The file /usr/include/cups/ipp.h is missing!
    The file /usr/include/cups/language.h is missing!
    The file /usr/include/cups/md5.h is missing!
    The file /usr/include/cups/ppd.h is missing!
    The file /usr/include/cups/raster.h is missing!
    Recreating symbolic links...
    Done.

    Verification complete.

    849 files examined. No problems were found.

    11 missing files/directories found during the verification process. They may be responsible for certain printing problems. Printer Setup Repair cannot replace these items. Please refer to the log file for a list of the missing files/directories. You may need to reinstall OS X to resolve your printing issues. Certain files and directories are deleted when using the Reset Printing System option. These files and directories, if required, will be recreated during normal printing.

    Sounds to me like you need to do an Archive & Install. I don't think any of those files are needed except when compiling a driver.
