This issue is currently under investigation by Apple engineers. Apple has been able to reproduce the this issue when a LaserWriter Select 310 is connected to a Macintosh Performa 6400/200 and is turned off while the computer is starting up. In this case, the Macintosh Performa 6400/200 computer will not be able to see the printer until the computer is restarted.
Important Note
--------------
It only occurs on Macintosh Performa 6400/200 computers. Macintosh Performa 6400/180 computers are not affected by this issue.
Workaround
==========
The only workaround to this issue, at this time, is to make sure the LaserWriter Select 310 printer is powered on before powering on the computer. After the Macintosh Performa 6400/200 finishes starting-up, you can power the printer on or off at any time.
