INITIALIZE COMMAND
[ESC] @, [ESC] WR
Function
Returns the printer to its initial state.
Format
[ESC] WR [LF] [NUL]
[ESC] @
Explanation
(1) The printer is returned to the same state as when the power is turned on.
(2) If the printer receives this command during printing, the printer prints the label
which is being printed, then performs initialization.
(3) After the Initialize Command is sent (or after printing is completed, if printing is
performed), the next command must not be sent within approx. 30 seconds on the
wireless LAN model or within 5 seconds on other models since the printer perform
initialization. In IrDA: TEC Protocol, if ACK/status transmission is specified by the
Issue Command, the printer returns an ACK, which indicates the command
process end, to the EOT after the printer is initialized. In RS-232C, when the
status response is specified, the printer returns the status (10H). After this status
is received, the next command may be sent. In IrDA: IrCOMM, IrDA: IrOBEX, RS-
232C, Bluetooth, or Wireless LAN, the printer does not return the status.
(4) To use IrDA interface for sending this command to the printer, only this command
should be sent. After the command is sent, the link should be terminated. Even
if the host does not terminate the link, the printer performs the termination process.
Therefore, after initialization is completed, the host should establish the link again.
(5) When receiving this command during data transmission, the printer is initialized
after transmission is completed.
Notes
(1) If a command error or communication error occurs when receiving the Reset
Command, an error message is displayed in the online mode. However, it is not
displayed in the SYSTEM mode.
(2) After the code of the Graphic Command ([ESC] SG) is received, the Reset
Command is not processed until the printer receives the data specifying the type
of data.
