• With the serial interface model, this command is executed even in
off-line or receive buffer-full state. However, with the parallel
interface model, this command is not executed in off-line or
receive buffer-full state because the printer is busy and unable to
receive this command from the host.
• The status is transmitted whenever the data sequence of
<10>H<04>H<n> (1 ≤ n ≤ 3, n = 5) is received even if it appears as
part of another command. For example,
