DEVICE STATUS
The status of the integral printer or an external printer
can be obtained by issuing a device status request. This
request would typically be made following a print opera-
tion or after examining bytes 5 and 6 of the terminal
status. The device status bytes are shown on page 8-7.
You request device status by issuing the following escape
sequence:
<ESC)&p <device code)"
where
<device code)
is either 4 or 6. Unless device code 4

minator. A typical device status request and response are
