I'll be calling but in the meantime, I sent the following email to the link given on the FAQ page.
Hello,
+This message is for technical support.+
+If you click the link below, taking you to one of many apple.com discussion forums, you will see that I, like many others, am having a problem with the latest Apple operating system (mac OS X 10.5.0 "Leopard") and the KM 2530DL printer. We need help and we need it fast. Many of us have tried a number of "possible" solutions and, while a few have succeeded, the majority of us remain printerless.+

+I am currently set up to print through an Apple Airport Extreme wireless base station. I have two other computers that also utilize this wireless setup. The other two computers have mac OS X 10.4.9 installed and have no issue with the printer. I have also connected the KM 2530DL directly to the updated computer but to no avail. And I, like everybody else, have frantically rebooted, unistalled drivers, reinstalled drivers, tried other drivers, turned firewalls on & off, powered down the printer et cetera and ad nauseam all without success.+
+Please help. There are many of us out there who are in dire straights without a printer. I have a backup printer (it worked fine) but many others do not.+
+It would be great if someone from Konica Minolta Technical Support entered into the discussion at the link posted above.+
+I look forward to your response directly or indirectly via the discussion forum.+
+Thank you,+
+M. Woodruff+
