This control cancels double-wide printing if double wide was selected with the Shift
Out control. The characters-per-inch setting returns to the previous value.
Cancel (ESC CAN)

Cancel is processed normally. Cancel does not change the current print position.
Turn Auto Sheet Feeder On or Off (ESC EM)
1B 19 NN
This command selects or deselects the Automatic Sheet Feeder (ASF). This
command must start and finish with a carriage return, line feed, or both; otherwise,
it will be handled as if it were printable data.
The following values are used for NN:
0 Disable ASF. Ejects any form loaded from bin 1, 2, or 3, and selects Manual
Sheet Feed paper path.
1 Selects bin 1 if no forms are loaded; otherwise, the next form is loaded
from bin 1 when data is received.
2 Selects bin 2 if no forms are loaded; otherwise, the next form is loaded
from bin 2 when data is received.
3 Selects bin 3 if no forms are loaded; otherwise, the next form is loaded
from bin 3 when data is received.
4 Selects the last bin in use after the Deselect ASF command. A form will be
loaded when data is received.
C Selects bin 1 for the first form; then selects bin 2 for all subsequent forms.
R Ejects the currently loaded cut-sheet form.
