10.10.4 INTERVAL/WINDOW SETTING AT THE INQUIRY/PAGE
Function Sets an interval and window of inquiry/page for the Bluetooth interface.
Format [ESC] BQ; aaaa, bbbb [LF] [NUL]
Term aaaa: Interval of an inquiry/page (Fixed at 4 digits)
bbbb: Window of an inquiry/page (Fixed at 4 digits)
Explanation (1) An interval and window related to the time for the printer to respond to an inquiry or
page from the host are set. When the printer is used in the environment where a
connection with the host takes time, the connectivity will be improved by making
the value of the interval smaller and the window larger.
(2) When the value of the interval is set smaller and the window larger for improving
the connectivity, the printer's power consumption will be increased.
compared with the printer which is used with the factory default setting, the standby
time and the number of issues will be decreased.
(3) This setting becomes effective when the printer is restarted after the parameter is
set and the printer power is turned off properly.
(4) In the LABEL mode (Mode = 0), RECEIPT mode (Mode = 1) or RECEIPT1 mode
(Mode = 2), the printer returns "38H" (setting completed) when the processing for
the Bluetooth module is completed successfully, and returns "39H" (setting error)
when failed. In the TPCL mode (Mode = A) or TPCL1 mode (Mode = B), the
printer returns "38" (setting completed) when the setting for the Bluetooth module
is completed, and returns "39" (setting error) when failed.
(5) When the value of the interval is smaller than the value of the window, the printer
returns "39" (setting error).
(6) In the case of the B-EP-GH32, when a value ranging from 4081 to 4096 is set, it
will be rounded to 4080 by the printer firmware.
Example To set the interval to 640 msec. and the window to 45.0 msec.
