Update: Christopher Cunningham writes: "I had the same problem. Quicken tech support told me to use an older print driver. I am using 8.3.3 and everything prints out fine." R. Russell Reed confirms that this is a general problem with Quicken and certain versions of LaserWriter 8.
Update: This problem apparently does not affect all users. In particular, Intuit's Quicken for Mac Product Manager reports that Intuit has been unable to duplicate this problem. It has also not happened to me. However, I have since gotten other confirming reports.
