Two commands are used in conjunction with multidrop mode. (See chapter 5 for more
information about printer commands.)
^Axx^D108
Sleep Mode: If xx=0 all printers in multidrop mode will sleep. Otherwise, XX
represents a printers address. Only the printer with this address will be affected.
^Axx^D109
Wake Mode: If xx=0 all printers in multidrop mode will wake-up. Otherwise, XX
represents a printers address. Only the printer with this address will be affected.
In wake mode, a printer will respond to all communications. When a printer is in sleep mode, it
will ignore all commands from the host except “wake up” (^D109) provided the address is
correct or the general address is used (xx=0).
Example commands:
^A0^D109
All printers in multidrop mode will wake-up and begin responding to all
communications from the host.
^A17^D108 If there is a printer in the network with an address of 17 (as determined by the
hardware switch settings), it will go to sleep. It will ignore all commands until it
receives a wake-up command or is restarted with the multidrop function
disabled.
