will go “low” (or an X-Off is sent) indicating the printer can no longer receive data.
This condition is called “Buffer Near Full.” will go “low” (or an X-Off is sent) indicating the printer can no longer receive data.
This condition is called “Buffer Near Full.” will go “low” (or an X-Off is sent) indicating the printer can no longer receive data.
This condition is called “Buffer Near Full.”
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 1MB bytes of data are being held (2.0MB 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.
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.
IEEE1284 PARALLEL INTERFACE
The parallel interface for the CL Series “e” printers is a Plug-In Interface Module that
can be installed by the user. It conforms to the IEEE1284 specification. It will
automatically detect the IEEE1284 signals and operate in the high speed mode. If it
does not detect the IEEE1284 signals, it will operate in the standard Centronics mode,
which is significantly slower. For this reason, an interface cable and host interface
conforming to the IEEE1284 specification must be present to fully utilize the speed
capabilities. This interface also operates bi-directionally and can report the status of
the printer back to the host.
