❏ For Bluetooth
®
interface models, if you establish a radio connection between the
host computer and the printer each time you start printing instead of maintaining
the connection, it may take a while between the time you send a print job and the
time that the printer actually starts printing. This happens because connecting the
host computer and the printer requires some time. The time required for
connection depends on the operating environment.
