The first two values are set through configuration of the machine, or the inserted expander cards; the
third value changes “dynamically” upon saving the graphic images and/or other objects.
~HS (Host Status)
The printer reports the status through three strings, where each begins with the character <STX> and
ends with the sequence <ETX><CR><LF>, just as the lines are separated by the host for easy
reading.
The format of the first one of these is:
<STX>aaa,b,c,dddd,eee,f,g,h,iii,j,k,l<ETX><CR><LF>
aaa: is a base 8 number that describes the communication parameters of the serial port. aaa is the
octal representation of the binary number a

a
7
indicates the handshake protocol. XON/XOFF when it is low (0), hardware when it is high (1).
a
6
indicates the parity. Odd when it is low (0), even when it is high (1).
a
5
indicates whether parity has been enabled. It has not when it is low (0), and it has when it is
high (1).
a
4
indicates the number of stop bits. Two when it is low (0), one when it is high (1).
a
3
indicates the number of data bits. Seven when it is low (0), eight when it is high (1).
b: is 1 when the machine is out of paper, 0 in other cases.
c: is 1 when the printer is in pause, 0 in other cases.
dddd: is a whole number of four digits that indicates the length of the current label, expressed in
dots.
eee: is the whole number of three digits that indicates the number of labels in the reception buffer.
f: is 1 when the memory buffer is full. 0 in other cases.
g: is 1 when the communications diagnostic mode is enabled. 0 in other cases.
h: is 1 when the current label is being processed. 0 in other cases.
iii: is always 000.
j: is 1 when the RAM is “corrupted.” 0 in other cases.
k: is 1 when the head is too cold. 0 in other cases.
l: is 1 when the head is too hot. 0 in other cases.
