5.1 Notes for using Bluetooth (RJ-4030 only)

If the printer is connected using Bluetooth, the printer may not be ready immediately after the port is opened.
When sending print data, wait at least 500 msec after the port has been opened before starting to send the
data.
In addition, if the port is continuously opened and closed, for example, when printing multiple pages, wait at
least 500 msec after the port is closed before opening the port the next time.
Once the print data for one page has been sent, do not close the Bluetooth port until printing is finished.
Since 32 bytes of data will be returned from the printer when printing is finished, close the port after it is
received by the host.
