CHAPTER 8 ESC/POS MODE (INTERFACE COMMANDS)
B-EP
Series
8-87
8.11.2 RESET
COMMAND
[ESC]
WR
Function
Returns the printer to its initial state.
Format
[ESC] WR [LF] [NUL]
Explanation
(1)
The printer is returned to the same state as when the power is turned on.
(2) When the printer receives this command during printing, it is initialized after issuing the
label which is being printed.
(3) After the Reset Command is sent (or after printing is completed, if printing is performed
when the Reset Command is sent), the next command must not be sent within 30 seconds
by the wireless LAN model or within 5 seconds by other models, because the printer is
initialized. 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 (34H 30H). After this status is received, the next command may
be sent. In IrDA: IrCOMM, IrDA: IrOBEX, USB, Bluetooth or Wireless LAN, the printer
does not return the status.
(4)
When this command is sent through the IrDA interface, 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
completing the transmission.
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.
