If you’re not programming in BASIC, check to see if you have an
equivalent statement in the language you’re using to suppress extra
carriage returns and line feeds from your data being sent out to the
printer. We want the data stream to be one complete line going to the
p
rinter.
USING THE RS232C SERIAL INTERFACE
1. Is the RS232C Serial cable connected securely to you
r
serial port on the PC
(
DB- 25S or DB-9S Male
)
and to the RS232C connecto
r
on the
p
rinter?
WARNING: Never connect or disconnect interface cables (or use a switch box)
with power applied to either the printer or the host. This may cause damage
to the interface circuitr
y
and is no

.
2.
Is the cable defective? At the very least, you should be using a “Null
Modem Cable,” which crosses pins in a specific manner. This should enable
your printer to print. But we recommend that you eventually use a cable
built to specifications as described in Section 6: Interface Specifications.
3.
Is the RS232 Interface Module installed in the printer? The “Se” printers
require the new Hi Speed Serial Interface (PN WCL40451)to take
advantage of the faster data transmission speeds. The older Serial
Interface Modules will work
,
but at a reduced ca

abilit
y
.
4.
Check for obvious errors in the data stream. Is the data properly framed
with the <ESC>A and <ESC>Z commands? See Section 5: Programming
Reference if necessar
y
.
5. If after sending your job to the printer, it only “beeps” and displays an error
message on the LCD display, you may have a configuration problem.
There may be some inconsistencies with the Baud Rate, Parity, Data Bits,
or Stop Bits in relation to your host computer. If you are confused as to
what the printer’s current RS232 settings are, print a Configuration Test
label(see Section 3). It will list all of the current printer configuration
settin

6.
If you still are unable to get printer output, try the Hex Dump as described
in Step 5 under the Parallel Interface troubleshooting. In this case, the
