Code 10

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 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 first 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 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 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 command was sent

before the line buffer was filled.
