4.3.1 Character codes
The ASCII code is used as the standard character code.
If the printer receives a character code not specified in the character code
table or not included on the print band, the code is changed
130
the space code
(X.20')
and no character is printed for the code.
If a character code from
X'AO'
to X'FE' is received in 7-bit mode, the WIF8 signal can be ignored
(regarded as
0)
by setting, and a character corresponding to
leach
code from
X'20'
to
X'7E'
is printed.
For the setting method, refer to
#Operator's
Guide.
When receiving character codes, the printer sequentially
load,s
them in its
internal buffer (IBF).
Characters corresponding to the
loade'd
character codes
are printed after a control code is received. The IBF is
cle,ared
after
printing.
The character code received next is for column 1.
4.3.2 Control codes
The line feed
(LF),
form feed
(FF),
and carriage return (CR) codes are control
~~
codes indicated in the area enclosed with a boldfaced line in Table 4.2.
The
printer starts an operation, such as printing and forms feed when the control
code is received.
(1)
LF code
(X'OA')
When receiving the LF code, the printer starts printing characters
corresponding to the received character codes from column 1. After
printing the characters, the printer spaces. If the number of character
codes received before the LF
code,is
less than 132 (or
136),
the remaining
characters are treated as spaces. If the LF code is received without
character codes, the printer does not print, it only feeds forms.
(2) FF code
(X'OC')
When receiving the FF code, the printer starts printing characters
corresponding to the received character codes from column 1. After
printing the characters, the printer feeds forms to the top-of-form
(TOF)
line,
or if FCB data is loaded, to the line with channel I.
If there is no channel 1 in the loaded FCB data, the printer feeds forms
to the first line on the next page.
For definition of the TOF and channel
1, see Section 4.4.1.
If the number of character codes received before
the FF code is less than 132 or 136, the remaining characters are treated
as spaces.
If the FF code is received without character codes, the printer does not
print,
it only feeds forms.
Even if the forms are positioned at the TOF
or channel-l line, the printer feeds forms to the next 'TOF or channel-l
line.
(3) CR code
(X'OD')
When receiving the CR code, the printer starts printing
ch,zxacters
corresponding to the received character codes from column 1. One of the
following modes are available for the operation after printing:
