SureMark Printers User's Guide
Settings described in this section apply only when the printer is connected to the
system with the RS-232 cable.
You must have power ON and paper installed in the thermal print station.
1. Open both the document cover and the receipt cover.
2. Press and hold both operator buttons until the Customer Receipt (CR) light
blinks rapidly.
3. Close the Document Insert (DI) cover. This is the front cover.
4. Close the CR cover. This is the rear cover. A menu is printed on the CR paper.
5. Follow the instructions on the menu to set the baud rate and the communication
protocol. The information provided in "RS-232 communications protocol
selection" describes the selections and their purposes.

RS-232 communications protocol selection

SureMark printers support the RS-232 protocol using either DTR/DSR or
XON/XOFF to control data transmission. XON/XOFF mode uses system and printer
software to control the flow of data. This is called flow control.
DTR/DSR control:
DSR definition
DSR is an output from the printer. It indicates when the printer is ready to
receive data.
DTR definition
DTR is an input to the printer. It indicates to the printer that the system is
ready to receive data.
DSR operation
A DSR signal becomes inactive when the printer is not ready to receive
data (for example, at power-on reset [POR] or when its buffer is full).
DTR operation
A DTR signal becomes inactive when the system is not ready to receive
data (for example, at power-on reset or when its buffer is full).
XON/XOFF control:
XON definition:
= DC1 (X'11')
XOFF definition:
= DC3 (X'13')
During XON/XOFF control, the printer transmits an XON every 3 seconds after a
POR completes to indicate the printer is ready to receive data. When the first
message is received, the printer stops transmitting the XON signal. The printer
transmits an XOFF when the RS-232 input buffer is 80% full after which it transmits
one XON when the buffer is 20% full.
