Control Codes
C.3 Control Codes
1.Null: Nul (X
'
00
'
)
No action. This code is ignored.
2.Bell: Bel (X
'
07
'
)
The buzzer sounds upon reception of this control code.
Note: If you select “OFF” from the buzzer setting item during initializa-
tion, this code is ignored when received.
3.Back Space : BS (X
'
08
'
)
The print position is moved back to the left single character space. In
the character enlargement mode, the print position is moved back to the
left double character space. In the condensed character mode, the print
position is moved back to the left single character space.
If the print position is at the left end, this code is ignored. If print data is
followed by this code, printing starts. If the succeeding data on the
same line is received, it is written over the data already in the print
buffer. If a condensed character setting is made, the single byte char-
acter width becomes 18 cpi and the print position is also moved back 18
cpi character spacing.
4.Horizontal Tab: HT (X
'
09
'
)
Moves the print position from the current position to the next horizontal
tab stop.
If no tab stops are set, the printer ignores this code.
5.Line Feed: LF (X
'
0A
'
)
All data in the buffer is printed and the paper is fed one line. If no data
precedes this code, the paper is advanced one line without printing any
data.
6.Vertical Tab: VT (X
'
0B
'
)
Prints all the data in the buffer and advances the form to the next ver-
tical tab stop position.
7.Form Feed: FF (X
'
0C
'
)
Prints all data in the print buffer and moves the form to the top of the
next form. The print position moves to the first character position.
If the print position is already at the top of the form, this code is ignored
