Notes on use
Time required until printing starts
If the host computer and the printer are not connected on a continuous basis but rather connected every time
the printer starts printing, some time may be needed for the printer to actually start printing after the host
computer commands printing. This pause is the time required for processing the connection between the host
computer and the printer.
After opening the port, leave an interval of 300 msec or more before sending data to the port.
Timing to shut the connection off
If a connection between the host computer and the printer is shut off while the printer is offline, it may not be
re-established. In this case, first clear the printer offline causes, and then try to re-establish the connection.
