When the printer is turned on, it is in the receiving state. When printing begins, it changes to the
“printing”
phase (phase type: printing state; phase number: printing), and the printer sends that phase status to the
computer. When printing has finished, the printer sends the “receiving state” phase status (phase type:
receiving state; phase number: waiting to receive) to the computer. Unless an error occurs during printing,
the printer sends the “printing completed” status.
⚫
With concurrent printing, printing starts even if a print command has not been sent from the computer in
order to print at high speed. At this time, care should be taken since the
“printing” and “waiting to receive”
phase statuses will be sent. (
