Upon receipt of this code, the printer erases from
its buffer the previously received character. This is
useful in correcting typing errors for programs that
send data both to a video screen and the hardcopy
printer. Remember that if you type more characters
than the printer can print on a line, the printer will
automatically start printing.
The printer handles this control code in exactly the
same manner as carriage return (control code 13)
except when a line feed immediately follows a
carriage return. The line feed code is ignored if it is
immediately preceded by a carriage return. The
default setting is 7.6 lines per inch.
Whenever a carriage return code is received, the
printer will print out the current contents of its
buffer, then clear the buffer to get ready for addi-
tional data.
This control code tells the printer to switch to the
double height character line. The control code can
be sent at any time on a line, it need not be the first
code received by the printer after a carriage return.
You cannot mix normal and double height charac-
ters on the same line. Once you select the double
height, the printer will remain in that mode until it
receives a carriage return or line feed. A line print
caused by a buffer full condition will not clear the
double height command. This means that the
“wrap around” print line will also be double height
if the double height command was sent before the
line buffer was filled.
This control code tells the printer to switch to
double width character printing. The control code
should be sent as the first character on a line. If it
is received after half the maximum characters per
line were sent then the printer will ignore all
characters on the last half of the line.
You cannot mix normal and double width charac-
ters on the same line. Once you select the double
width, the printer will remain in that mode until it
receives a carriage return or line feed. A line print
caused by a buffer full condition will not clear the
double width command. This means that the “wrap
