(STANDARD)
DLE DC4 n d1...d7 (when n = 8)
[Name] Clear buffer(s)
[Format] ASCII DLE DC4 n d1...d7
Hex 10 14 n d1...d7
Decimal 16 20 n d1...d7
[Range] n = 8
d1 = 1, d2 = 3, d3 = 20, d4 = 1, d5 = 6, d6 = 2, d7 = 8
[Description] • Clear all data stored in the receive buffer and the print buffer.
• Transmits the following data block to the host.
Header: Hexadecimal = 37H / Decimal = 55 (1 byte)
Status: Hexadecimal = 25H / Decimal = 37 (1 byte)
NUL: Hexadecimal = 00H / Decimal = 0 (1 byte)
• After this command is executed, the printer selects the paper roll as the paper
source and enters the standard mode.
[Details] • This command is effective even when the printer is disabled with ESC = (select
peripheral device).
• If another command is being executed while this command is processed, the
execution of the other command is stopped.
• If this command is processed in a slip insertion waiting state, the waiting state is
cancelled. This process is same as for DLE ENQ 3.
• If this command is processed when a recoverable error occurs, the printer
recovers from the error state. This process is same with DLE ENQ 2.
• If this command is processed in page mode, the printer enters the standard
mode. In this case, the printer sets the default values to ESC W (only for ANK
model).
• This command does not affect and initialize the setting values for other
commands (except for ESC W in a page mode).
• With a serial interface model, this command is executed even when the printer is
offline, the receive buffer is full, or there is an error status.
• With a parallel interface mode, this command cannot be executed when the
printer is busy. This command is executed even when the printer is offline or
there is an error status when DIP switch 2-1 is on.
[Notes] • This command must not be used in a system using this printer and the EPSON
OPOS driver.
• If print data includes this command string, the printer performs this command.
The user must consider this.
• This command should not be used within the data sequence of another
command that consists of 2 or more bytes.
