Hey, everyone.
I made some instructions that are as simple as I can possibly imagine. It is exactly what I did and I am able to print to my 1020. No guarantees that this will work for you and if you know absolutely nothing about the command line it may be better to steer clear. That being said, it's so cookie-cutter that you should be able to do it regardless.
Standard disclaimer: this may not work for you and could potentially screw up your Snow Leopard install (although that's probably pretty unlikely).
Download the two files here:
http://idisk.mac.com/geoffchapman-Public?view=web. One is a text file with the instructions and the other is a .zip file - expand it and you will find the Automator app I describe in the text file. FYI this app does not do the install for you (although I wish it did) - it's only to help with a small bit once you've got everything done.
Please post back with your system config and whether or not it worked. I am going to be around today - I'll try to get back to any quick questions. But I am going to be out of the country for two weeks starting tomorrow so at that point you're on your own.
Good luck!
