Clear print buffer

[CAN]
The [CAN] command clears the print buffer and any unprinted information in the
printer received before the [CAN]. The CAN command does not restore default
conditions. It only clears the print buffers.
If the input buffer is not being processed (because the printer is out of paper or the
form is not inserted), the CAN command will not be processed until after the error is
cleared.

Return a status to the host during processing
Serial/Parallel, IEEE 1284
[SOH]<n>...
The command can be placed in the print data and, when processed by the printer,
will return a progress status marker. The value of <n> can be any 8-bit value. It
is returned to the host unaltered. The intent is for it to be a sequence number.
The command can be used to track the print progress of the printer or verify that
the data has been printed.
The command is a line terminator and causes the printer to print all previous
data. If a normal line terminator (like a [CR]) is not supplied, right justify and
autocenter will not function correctly. All data will be left justified. [ESC] q does
not perform a [CR] or [LF] function.
