Upon receipt of this code, the printer erases from its
buffer the previously received character. This is use-
ful 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 automati-
cally 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 car-
riage return. The line feed code is ignored if it is im-
mediately preceded by a carriage return. The default
setting is 7.4 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 additional 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 fi rst
code received by the printer after a carriage return.
You cannot mix normal and double height characters
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 fi lled.
This control code tells the printer to switch to double
width character printing. The control code should be
sent as the fi rst 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 characters
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 around" print
line will also be double width if the double width com-
mand was sent before the line buffer was fi lled.
