Fix EFI Fiery E10 Driver on Mac OS X 10.6 Snow Leopard

I’ve had all sorts of issues installing the Fiery E10 driver (installed in a KM Copier) to work under 10.6 – after installing it, the Printer preference pane would have a yellow warning triangle and when you opened the printer window, it’d say something along the lines of the printer is not properly installed.

It turns out that it’s a simple matter of fixing the permissions.

Download the driver, either from the web page published by your printer, or from Konica Minolta Europe.
Install it as normal (Oh KM, why do you insist on using a non-standard non-OS X .pkg installer?)

Once it’s installed, type the following two lines into the Terminal, entering your admin password when prompted:

sudo chown -R root:wheel /usr/libexec/cups/filter
sudo chown -R root:admin /Library/Printers/efi

Now, add the printer as normal. If you have already installed the driver and added the printer, there’s no need to remove it and add it again, this will get it working.

  1. Fiery have a Universal Fiery Print Driver up that supports 10.7.
    Unless you’re using fancy features, this may even be a better driver than the “full featured” driver as it doesn’t load any additional binaries, it seems to be all in the PostScript PPD.


    From the blog post:

    The Fiery Express driver will support the following features for Fiery printing:
    • Duplex
    • Stapling
    • Output Paper Size
    • Color Mode
    • Composite Overprint

    I’d warrant that this is probably all the functionality that you’ll need 90% of the time anyway.
