READY/BUSY INTERFACE SIGNALS
FG (Frame Ground)
TD (Transmit Data) - Data from the printer to the host computer. Sends X-On/X-Off characters
or status data (bi-directional protocols).
RD (Receive Data) - Data to the printer from the host computer.
RTS (Request to Send) - Used with Ready/Busy flow control to indicate an error condition.
RTS is high and remains high unless the print head is open (in this case, RTS would return to
the high state after the print head is closed and the printer is placed back on-line) or an error
condition occurs during printing (e.g., ribbon out, label out).
CTS (Clear to Send) - When this line is high, the printer assumes that data is ready to be
transmitted. The printer will not receive data when this line is low. If this line is not being used,
it should be tied high (to pin 4).
DSR (Data Set Ready) - When this line is high, the printer will be ready to receive data. This
line must be high before data is transmitted. If this line is not being used, it should be tied high
(to pin 20).
SG (Signal Ground)
DTR (Data Terminally Ready) - This signal applies to Ready/Busy flow control. The printer is
ready to receive data when this pin is high. It goes low when the printer is off-line, either
manually or due to an error condition, and while printing in the single job buffer mode. It will
also go low when the data in the buffer reaches the buffer near full level.
