Baud Rate; Word Length; Stop Bits - Printronix P5000 Series Setup Manual

If the host keeps sending data after an XOFF is sent, the printer firmware
will continue to send an XOFF for every 16 characters received.
When cleared, the printer will resume receiving data (XON). The data
does not have any End of Text codes; XON / XOFF is a non-block
protocol.
•
ETX / ACK. End of Text / Acknowledge. The host controls the flow of
communication to the printer by sending a block of data and ending the
block with an End of Text (ETX) signal. When the printer receives the
ETX signal, it will acknowledge the ETX, thereby acknowledging it has
received the entire block of data.
•
ACK / NAK. ACK means acknowledge; the device acknowledges it has
accepted a transmission. NAK means a negative acknowledge; the
device did not receive the transmission.
•
DTR. Data Terminal Ready. The printer controls the data flow by sending
this hardware signal to the host. If there is enough room in the printer
buffer, the printer will send a high signal; if the buffer is full the printer will
send a low signal. DTR tells the host if it is safe to send more data. If the
host sends data during an unsafe condition, data will be lost.

Baud Rate

Sets the baud rate of the serial interface in the printer. Baud rate is the speed
at which serial data is transferred between the host computer and the printer.
The choices for the RS-232 and RS-422 interfaces are 600, 1200, 2400,
4800, 9600, 19200, 38400, 57600, and 115K Baud. The default is 9600 baud.
NOTE: If you select a baud rate that is 19200 or greater, you may need to
increase the Buffer Size in K parameter from the default (8 Kbyte), to
improve performance.

Word Length

Sets the length of the serial data word. The length of the data word can be set
to 7 or 8 bits, and must match the corresponding data bits setting in the host
computer. The default is 8 bits.

Stop Bits

Sets the number of stop bits in the serial data word. Either one or two stop bits
can be selected. The setting must match the corresponding stop bit setting in
the host computer. The default is 1 bit.
Parity
Set for odd parity, even parity, mark, sense, or no parity. The setting must
match the corresponding parity setting in the host computer. The default is
None.
