The computer must have been pushing data to the printer too quickly over the USB 3.0 port; the printer got a garbled postscript instruction and everything went downhill from there.
that doesn't compute. USB 3 uses a different (new) set of 5 pins on the same connector, but the original 4 pins are still there and support USB 1 and 2. A more likely explanation is that the device driver for this printer isn't enumerating USB devices correctly, or isn't handling some additional usb3 related port-specific status information correctly, so its getting confused.
The whole USB spec is a ungawdly mess now with layers and layers of BS piled up on a shakey foundation, and complicated APIs to access all this.
Is that why my DD-WRT router keeps forgetting about my USB printer? <g>
