Chapter 3: Printer Menus and Configuring Your Printer
Serial I/O Category
Serial Interface is a style of host computer-to-printer I/O communications. It
requires certain parameters to be properly set in order for the printer and host
computer to communicate.
Baud
The Baud parameter allows the user to set up the printer to receive data at
different transmission speeds. The baud rate must be the same value at both
ends of the communication line. 9600 is the default selection.
Data Bits
You can choose the number of data bits per byte. 8 bits is the default selec-
tion.
Stop Bits
This parameter sets the number of serial stop bits. 1 is the default selection.
Parity
Parity is a method the printer uses to verify that each byte of data it receives is
exactly what the host computer transmitted. When selected, it keeps track of
the number of high bits in each byte (either odd or even). Default is None.
The printer must match the parity of the host computer.
8th Bit
If 8 bits per byte is selected under Data Bits above, you use this parameter to
determine how the 8th bit is to be used. If this bit is to be ignored, the param-
eter should be set to unused. If the bit is to be used, the parameter should be
set to Data. Data is default, used for 8-bit characters.
Protocol
The printer and host computer must establish common signals, understood by
both units, for indicating when to send new data and when to stop sending
data. For IPDS, this parameter allows the serial protocol to be set to either
Ready/Busy or XON/XOFF. For all other printers, there are six additional
protocols. The eight protocols are:
Ready/Busy
(Default selection)
Xon/Xoff
Enq/Ack
(Enquiry/Acknowledge)
Etx/Ack
(End of Text/Acknowledge )
Etx/Ack/Nak
(End of Text/Acknowledge/Neg. Acknowledge )
Ack/Nak
(Acknowledge/Negative Acknowledge )
Xon/off/Etx/Ack
(XON/XOFF/End of Text/Acknowledge )
Xon/off/Enq/Ack
(XON/XOFF/Enquiry/Acknowledge)
The above protocols are explained in detail in the Applications Manual.
