Bit 6 Bit 5 Printer behaviour
0 0 Switches the Station1 or Station2 LED off as specified in bits 1 and 2. If both
are off, after this sequence has been executed, any pending book operator
commands will be cancelled
1 0 Switches the Station1 or Station2 LED off as specified in bits 1 and 2. After
this sequence has been executed, the book operator command becomes
pending and is stored.
0 1 Switches the Station1 or Station2 LED on as specified in bits 1 and 2.
Pending book operator commands are not cancelled
1 1 Switches the Station1 or Station2 LED on as specified in bits 1 and 2. This
sequence always enables the book operator command.
If both operators are booked (Station1 and Station2 LEDs on), the printer will be
assigned to the first operator to press the key, canceling the other pending book
operator command.
If the key corresponding to the unbooked operator is pressed, the printer ignores the
action and does not answer.
This behavior gives priority to the manual book operator command (ESC _).
If automatic operation booking is selected (ESC .), the LEDs do not light up even if
parameter n indicates power-on: to make the LEDs light up, the LED on command
must be sent separately from the book operator command.
A pending book operator command does not block any printer function.
The command is not accepted (command specification error) if it is sent inside a
printing field.
