How to print from Google Docs in Safari?
I have not found a way to get the print dialog box to appear in Safari.  Instead I have created a script that will check when something is downloaded and see if it is from Google Docs. If it is then the document will be opened in Preview with the print dialog box. Basically giving you similar functionality you have in Chrome. You can then print it as you normally would.

Here's the script. Save it to /Library/Scripts/Folder Actions Scripts/:

on adding folder items to this_folder after receiving added_items
    repeat with i in added_items
        set myPath to the POSIX path of i
        if myPath ends with ".pdf" then
            set myLocation to (do shell script "mdls -name kMDItemWhereFroms " &amp; the quoted form of myPath)
            if myLocation contains ".google.com" then
                tell application "Preview"
                    activate
                    print i with print dialog
                end tell
            end if
        end if
    end repeat
end adding folder items to


The script will need to be added as a Folder Action. Follow instructions below:


Navigate to the Downloads folder
Right click on the Downloads folder and select Services&gt;Folder Actions Setup





Select the script that saved and click Attach
Make sure Enable Folder Actions is checked in the upper left
