3.1 GENERAL
DESCRIPTION
This chapter describes details regarding the interfaces between the host and the printer. The printer
configurations are as follows:
• IrDA + USB + RS-232C model
• IrDA + USB + Bluetooth model
• IrDA + USB + Wireless LAN model
The interfaces between Bluetooth and wireless LAN can be optionally upgraded:
• RS-232C
Æ
Bluetooth
• RS-232C or Bluetooth
Æ
Wireless LAN
• RS-232C
Æ
RS-232C + Bluetooth
• RS-232C
Æ
RS-232C + Wireless LAN
• Bluetooth
Æ
Wireless LAN
IrDA supports the following three protocols. Each of them is independently described on later pages.
• TEC Protocol
• IrCOMM (9-WIRE)
• IrOBEX
The printer interface is automatically switched between IrDA and RS-232C/Bluetooth/wireless LAN on
the following conditions:
•
IrDA + USB + RS-232C model
When the RS-232C cable is connected to the printer, the printer interface will be switched to the
RS-232C interface. When the RS-232C cable is disconnected, the interface will be switched to
IrDA.
•
IrDA + USB + Bluetooth model or IrDA + USB + Wireless LAN model
Usually, IrDA interface is standing by for communications. When data is sent from Bluetooth
interface or wireless LAN interface, the printer interface is automatically switched to the appropriate
interface.
When the printer enters the power save mode after the termination of a communication by
Bluetooth or wireless LAN interface (when five minutes have passed after the termination), the
printer interface will return to IrDA.
If data is sent to the printer by Bluetooth or wireless LAN interface during the communication by
IrDA, the printer interface will be automatically switched to Bluetooth or wireless LAN, and
consequently the communication by IrDA cannot be made successfully.
Notes
When the RS-232C is used for communications, the RS-232C cable must be connected
to the printer before the power is turned on.
