Select Peripheral Device
Selects or cancels a peripheral device designated by the value of n. When the
printer is not selected, it reads all data but performs nothing except the Real
Time Status Transmission or Real Time Request to Printer commands. Even
though the printer is not selected, it may go offline through manual printer
operation.
Use internal switch pack settings to determine which value of n is selected. For
more information, see “Switch Entry Mode” in section 3.
