~HB

When the
~HB
command is sent to the printer, a data string is sent back to the host. The string starts with an
<STX>
control code sequence and terminates by an
<ETX><CR><LF>
control code sequence.

Battery Status

This command only responds to mobile printers.
Format:
~HB

Parameters

When the printer receives the command, it returns:
<STX>hh.hh,bb.bb,bt<ETX><CR><LF>
<STX>
=
ASCII start-of-text character
hh.hh
=
current head voltage reading in integers
bb.bb
=
current battery voltage reading in integers
bt
=
battery temperature in Celsius
<ETX>
=
ASCII end-of-text character
<CR>
=
ASCII carriage return
<LF>
=
ASCII line feed character
  • This command is used for the power-supply battery of the printer and should not be confused with the battery backed-up RAM.
  • For a more precise voltage reading, you can use the power.voltage SGD command, which returns a value to the nearest hundredths of a volt (X.XX).
