The receiving buffer will not be able to receive more data again until a Buffer
Available condition occurs. This takes place when the receiving buffer has
emptied so that only 56K bytes of data are being held (8K bytes from being
full). At this time, DTR will go high or an X-On is sent to tell the host that it
can again receive data. See Fig. 3-2
All printer error conditions, (i.e., label out, ribbon out), will cause the printer
to go busy (DTR low or X-Off) until the problem is corrected, and the
printer is placed on-line. The printer will also be busy if taken off-line from the
front panel.
