When the LaserWriter Select 310 printer is first powered on, the serial port with binary protocol enabled is the default communication port. If any character is received over the Centronics parallel port, the parallel port with binary protocol and a serial back channel automatically becomes the default port. If you want to change the communication port back to serial mode after a job has been sent over the parallel port, you should power down and then restart the printer. Similarly, if you wish to change printer drivers, you should power down and then restart.
IMPORTANT
It is better to operate the LaserWriter Select 310 printer in either a serial or a parallel communication environment than to transmit both
serial and parallel data. Attempting to operate in both environments may cause unpredictable results. ▲
