Section 1. INTRODUCTION
The TELPAR SP·328 is a fast, low cost, narrow 40 column industrial printer. The SP-328 will
print at a paper feed rate of 2 inches per second.
The SP-328 can provide a variety of output formats on the standard 2.350" wide thermal paper.
Standard programming includes 11X28, and 22X28 dot matrix characters The SP-328 is also
capable of high density graphics. The SP-328 is equipped with a USB interface, RS-232
interface with a 4 position terminal connector, and a parallel interface connector.
Low maintenance is assured by TELPAR's reliable design, ribbonless thermal print technology.
The SP·328 also includes a built-in diagnostic self test and a 31K data buffer).
The printer weighs 4.5 pounds including the paper supply and mounting frame. It is housed in a
rugged 16 gage steel enclosure. It operates through -40 to +140 degrees Fahrenheit with a
constantly regulated print intensity control.

2.2 Unpacking and Inspection
Carefully unpack and inspect your SP-328 for any damage which may have occurred in transit.
Should any damage have occurred, notify Telpar. Specify the nature and extent of the damage.
Before installing or operating the printer, check the following:
1. Ensure that the primary power setting is correct for your installation.
2. Ensure that the printer mechanism and paper path are clear of all packing materials
and any other foreign matter.
3. Ensure that paper is installed. D0 NOT OPERATE the printer without paper. Refer to
Section 2.4 for paper loading instructions.

2.3 Power and Interface Connections
The Power connector, J6, is located on the rear of the printer.
Pin designations for the power connector J6:

2.4 Paper Loading
To allow access to the printer paper supply, push the spring loaded rectangular latches
inward (together) and pull forward to release the printer access panel. Install a new roll
of Telpar approved paper (thermal side UP) on the paper spindle. Fold paper back on
itself to form a straight and clean edge, and feed the leading edge of the paper directly
into the paper input slot. The paper will automatically feed paper through the
mechanism several inches. Use the feed button to advance paper through the bottom
take-up slot in the bezel - feed an appropriate amount of paper through the printer to
allow the installation of the paper onto the Paper Take Up Journal. To load paper onto
the take up, unscrew the fastener holding the left side guide plate and pinch rod. Install
paper between the main take up shaft and pinch bar and screw the fastener back onto
the take up spindle. Manually rotate the take up mechanism as shown to remove
excess slack in the paper.

Section 3. INSTALLATION
3.1 Power Up and Self Test
The operating controls of the SP-328 have been kept to a minimum. A convenient self-test
feature allows the operator to quickly determine that the printer is operating correctly.
To activate the self test feature hold the feed button while switching the power switch from the
off position to the on position. After one beep release the feed button. The self test will begin.
The SP-328 enters self test mode and prints out self test page which includes a graphics
pattern, configuration information, and character tables.
For the highest quality output and maximum thermal headlife, it is recommended that only
Telpar qualified thermal paper is used.

Section 4. INTERFACE SPECIFICATIONS
4.1 Serial Interface Specifications
The SP-328 can be used as either a serial or parallel device without requiring any switch or
jumper settings. The SP-328 will automatically detect the interface which is sending data and
produce the appropriate printout. The serial Interface parameters are factory set internal to the
printer firmware. Serial interface parameters must be specified prior to shipment. The standard
factory setting for the RS-232 serial interface is 9600 Baud, No Parity, 8Data Bits, 1 Stop Bits.
RS-232 Terminal Connector Serial Interface:
Pin Signal Description
1 TXD Data Output from the printer to the host.
2 RXD Data Input to the printer.
3 GROUND Signal ground
4 BUSY -10V when printer is unable to receive data.
There are two conventions used in the RS-232C interface; these are Data Terminal Equipment
(DTE) and Data Communications Equipment (DCE). Examples of DCE are modems,
multiplexers, and telephone data line interfaces. All other equipment which originates or
receives data such as terminals (including the SP-328) or computers is DTE. If two pieces of
DTE are to be interconnected it is necessary to transpose TXD and RXD as well as DTR and
CTS in the cable. This type of cable is called a null modem cable and must be used if the SP-
328 is to be connected to a host computer's serial port.

4.3 Flow Control
The SP-328 employs a 31 K byte data buffer to allow the host computer to rapidly transfer data.
Under some circumstances it may be possible to completely fill the buffer. When the buffer is
within 50 bytes of being full, the SP-328 signals the host computer to pause until a line of data is
printed, or until the buffer is under the 50 byte limit The flow control information is sent to the
host using hardware and software protocols.
The hardware protocol uses the BUSY line of the parallel interface and the BUSY line of the
serial interface. These pins are asserted or negated as necessary to turn off and turn on the
flow of data. There is an optional (factory set internal to the printer firmware) software protocol
for RS-232 serial which uses the XON and XOFF ASCII characters (^Q and ^S) which are sent
back to the host to start and stop the data stream. Some host systems may not support one or
both of these protocols.
