Paper roll Miscellaneous commands DLE DC4 (fn = 2)
Ver. 10.05 p. 389
With a parallel interface, if the printer is BUSY, this command cannot be used in the following states.
When DIP switch (BUSY condition) is on: receive buffer full
When DIP switch (BUSY condition) is off: offline, receive buffer full, or error status
This command is effective when the printer is disabled by ESC = (select peripheral device).
All information and data stored in RAM will be deleted by processing this command.
When the printer has executed setup of power off processing, the printer transmits the power-off notice
as shown below to the host.
Maintenance counter values are maintained by executing this command; therefore the maintenance
counter values will be more accurate if the user uses this command before turning off the power switch.
When you use this command, obey the following rules.
When host PC transmits the function data, transmit the next data after receiving the corresponding
data (header ~ NULL) from the printer.
When operating with a serial interface, be sure to configure operation so that the host computer uses
the printer only when it is READY.
When operating with a parallel interface, the data sent by this function (starting with Header and
ending with NUL), as with other data, is first stored in the send buffer, then output in sequential order
when the host computer changes to the reverse mode. Note that the send buffer capacity is 99 bytes,
and any data exceeding this volume limit will be lost; therefore, when using this command, it is
important to configure the operation so that the host computer’s change to the reverse mode and the
subsequent status send/receive process is performed quickly.
Power-off notice Hex Decimal Data
Header 3BH 59 1 byte
Identifier 30H 48 1 byte
NUL 00H 0 1 byte
