Control Codes
BEL (hex.07)
(dec.7)
Sounds acoustic signal.
BS (hex.08)
(dec.8)
Print contents of line buffer, then move the print head one position back. When auto right
justification is selected by code sequence ESC a<3>, <BS> will be ignored.
CAN (hex.18)
(dec.24)
When the printer receives this code, the print buffer is deleted. This code only clears the
contents of the print buffer; it does not affect any control codes which have previously
been sent to the printer.
CR (hex.0D)
(dec.13)
When the printer receives this code, it prints any data in the print buffer and resets the
line pointer to the left margin.
Code CR can also give a line feed if automatic line feed is selected. Refer to the
Operator’s Manual.
DC1 (hex.11)
(dec.17)
The control code DC1 switches the printer into Online Mode. If the printer has been set
Offline with the control code DC3, then DC1 is the only control code which can be carried
out. DC1 has no effect if the printer has been set Offline via the control panel.
DC1 and DC3 have no effect if the Centronics interface signal SELECT is switched off
(LOW).
DC2 (hex.12)
(dec.18)
Reset condensed print mode.
DC3 (hex.13)
(dec.19)
The control code DC3 switches the printer into Offline Mode. If the printer has been set
Offline with the control code DC3, then DC1 (switching printer Online) is the only control
code which can be carried out. If the printer has been switched Offline via DC3, it can
only be switched into the Online mode again using DC1 and not via the control panel.
DC1 and DC3 have no effect if the Centronics interface signal SELECT is switched off
(LOW).
DC4 (hex.14)
