I still have Snow Leopard on a hard drive so I searched for the older version. I think I found it at Download Automator Fun Apps Set 1 for Mac - Set of 24 Automator applications. MacUpdate.com but unfortunately Lion identifies it as Power PC. Unless someone comes up with a Rosetta alternative that one is out of the question.
I am not much of an AppleScripter but I wonder if it is possible to use AppleScript to define the printer before running that action. I took a cursory look in Automator but did not find anything that looked appropriate.
Thanks I will check that out. I think that what is happening here is that the action step itself is PowerPC code. It will run on both but running on Intel requires Rosetta. If it were a Universal Binary it would have both the Intel and Power PC code. Universal binaries will generally run under Lion because they have both Intel and Power PC code. It just runs the Intel code under Lion.
I found this via Google. I'm not sure whether is safe to download or use though.
