I don't really know which post to respond to, so I will post here.
There is a way to get the PPDs without PAHU mailing them you. It is rather geeky, but that is part of the fun.
Grab the installers if you haven't already done so and mount the disk image. Look in the MacOSX10.7- folder, then in the Packages folder. You will find the file Dell C1760 C1660 Print Installer.pkg. That is the file we will start with.
Open the Terminal (/Applications/Utilities). We need an empty folder to work with, so let's make a folder "inflate". At the Terminal prompt, enter
mkdir ~/inflate
and hit the Enter key. That will create a directory "inflate" in your Home folder. Next we want to tell the Terminal to use that directory. Enter
cd ~/inflate
and hit the Enter key.
Now we will inflate that installer file so we can work with it. In the Terminal enter the command
xar -xf make sure there is a space after -xf.
Now drag the Dell C1760 C1660 Print Installer.pkg file onto the Terminal window. It will fill in the compete path to the file. Hit the Enter key.
Next, go to inflate you created earlier in your Home folder. Find the file installation files.pkg. Right-click (Control-click) on that file and choose Show Package Contents. You should now see four files. Right-click (Control-Click) on Payload and choose the option to Open with > Other... That will bring up a navigation window. The application you want to choose is /System/Library/CoreServices/Applications/Archive Utility. Select that application and hit the Open button. The files will magically expand and you will find a folder Library with all the Dell files and the PPDs.
Well, that may not be as easy as asking PAHU to mail you the PPDs, but it is something you can do without exposing your e-mail address or waiting for PAHU and his good nature to send you the files.
