The June 3 Info Alley poses the following question: "I just installed Color StyleWriter 2500 software (v2.2.1) on my new Power Macintosh 4400 and 6500 computers, and now my print jobs get stuck in the queue of the Desktop Printer. I can get jobs to print by stopping and then resuming them - at which point they will then move into the active part of the Desktop Printer queue. What is happening?"
The answer involves possibly having mixed versions of the desktop printing software installed and some quirks of Apple's Extensions Manager utility. It can affect printers beyond the 2500. Check the Alley article for more details.
