DEVICE STATUS
The status of the integral printer or external device can be obtained by issuing a device
status request. This request would typically be made following a print operation or after
examining bytes 5 and 6 of the terminal status.
You request device status by issuing the following escape sequence:
Ec &p <device code> A
where <device code> is either 4 or 6. <device code> 6 returns status on the integral
printer, while 4 returns status on the external device or integral printer depending on the
setting of the Pr i nt erCode4 field in the Terminal Configuration menu.
If <device code> is any value other than 4 or 6, the escape sequence is ignored.
The terminal responds with the sequence Ec \p<device code>, followed by three status
bytes followed by a terminator. A typical device status request and response are illustrated in
figure 8-10.
