Man, what a pain. I thought about suggesting this to you earlier, but now I definitely would do this. Just set up a cheap computer and run XP and print from there. You should be able to do that for less than $300-$400. Do all your work on your new Mac. Then either preferably through a network, or through just a USB external drive move your finished files. Be a lot easier and faster and probaby cheaper than dealing with all the headaches. I dual-boot many OS's just for this reason. For the same reason, I avoid "upgrades" to my OS, hardware, firmware, etc. If everything is working, I'm in no hurry to change ANYTHING.
Good luck
