This value is stored in the EEPROM in the printer so that it is not lost when
the printer is reset.
Status Sent to System
RS-232 Syntax:
ESC ) n or X'1B29;n'
where:
n Select function.
Bit # ↓ Function Bit=0 Bit=1
LSB 0 Print Buffer Empty/Full Yes No
1 Reserved Yes No
2 Front Document Sensor Change Yes No
3 Top Document Sensor Change Yes No
4 After status byte 6 is incremented or
status byte 3, bit 7, is set
Yes No
5 Cash Draw Sensor Change Yes No
6 Key In Use Yes No
7 Cover Open Yes No
Remarks:
Bit 4 can be used in place of the Command Complete. When the buffer is
empty, the system can assume that everything stored in the printer has
been completed. To enable these status messages, unsolicited status must
be enabled. See “Asynchronous (Real-Time) Commands” on page 155.
Select Character for Reprinted Lines
RS-232 Syntax:
ESC + n or X'1B2B;n'
where:
n The ASCII representation of the character printed in the first
character position on the print line when recovering from a home
error. This occurs in impact print stations only.
Default:
n = X'2A' (This is an asterisk (*) in most code pages.)
Remarks:
The value is stored in EEPROM to prevent loss when the printer is reset.
The default value after the reset is the value last sent.
Reinitialize the Printer
RS-232 Syntax:
ESC @ or X'1B40'
Purpose:
Reinitialize all printer settings to their default values and reset the impact
printhead.
Remarks:
