Read carefully Before Using NP-345
Wrong handling of the printer may cause its performance declined and the product damaged.
Please read the notes below before handling.
1. Static discharge prevention must be made for installation and removal of the printer to
protect IC and other electrical parts. Connect it to the earth ground. It is also requested to
remove the static from body of the person before handling, especially, the input terminal.
The main unit should be grounded for the measure against ESD etc.
2. Avoid excessive force to the input terminal for handling.
3. When any type of paper, other than specified in this manual, is used, it may cause
deterioration of the print quality and thermal head life.
【Examples of troubles】
1) Print quality deterioration by using low sensitivity paper.
2) Thermal head wears due to roughness of paper surface.
3) Sticking between heat receipt layer and thermal head, and vibration noise during printing.
4) Print ink disappears on low print durability paper.
5) Electrolytic corrosion on thermal head due to low quality of heat receipt layer.
4. Avoid printing with no paper loaded. It damages platen and thermal head.
5. Do not scrabble thermal head with sharp edge or something hard, or give impact. The heat
element may be damaged.
6. Set the power of printer off before connecting or removing connecters.
7. When printing in high speed under low temperature and high humidity environment, the
paper may be stained by moisture that appears from paper, or the printer may have
condensation. Avoid dew from dropping down to the thermal head that may cause electrolyte
corrosion. Turn the power off until any dew is removed.
8. The printer is not protected from water or dew formed. Do not water the printer or handle it
with a wet hand, which may cause damage to the printer due to short circuit, or heat or fire.
9. The printer is not protected from dust or dirt. If it is used at dusty place, the thermal head
may be damaged or paper feed is not operated properly. Please take appropriate
countermeasure when printer used at dusty place.
10. When cooling the printer with a fan, please set air flow to avoid the printer’s paper exit from
being inhalation –of- air mouth.
11. Reflection type of infrared ray sensors are used at some locations in the printer. Direct sun
light may cause mal-function of printer. Avoid from such a location for installation.
12. This printer does not support any operations caused by the commands or control commands
not specified in this manual.
13. This printer does not support any operations caused by the commands or control commands
not specified in this manual.

Printing in the page mode starts only when receiving the print command (FF). For the detail
of the commands, please refer to the section 5.5.
2.4 Power supply specifications
1) Voltage: DC24V +/-5%
2) Consumption current
NP-345
Standby Approx. 0.1A
At printing ASCII (About 16% print ratio) Approx. 1.7A
At printing bit image (Max.100%) Approx. 7.8A
Notes:
1. Thermal printer runs a large excessive current for printing. Please use a power supply
with good response for print quality and capable of running high peak current.
2. When the power supply cable is excessively long and its diameter is small, voltage drop
may occur and cause error. For this reason, a short cable with large diameter is
recommended (above AWG#18). If such a cable is not available, connect a cable near
the printer and locate a low ESR electrolyte condenser in 2200 - 6800μbetween the
power supply and ground. The voltage
2.5 Reliability
1) Head life: Average resistance change ratio; less than 15% excluding dust and foreign
objects.
Pulse : More than 100 million pulses (for recommended paper)
Wear distance: More than 50Km (for recommended paper)
2) Operation environment: Temperature, 0 - 45°C,
* Print guaranteed: 5 - 40°, Should not be condensed
3) Storing environment : Temperature - 20 ~ 60°C
* For a long storage, place paper between head & platen
4) Safety regulation : CE mark
UL 60950
5) EMC
EMI : EN55022
VCCI :ClassA
FCC :ClassA
EMS : EN55024
Note 4: Thermal printer runs high transient current for printing. For this reason, it is
recommended to use such a power supply that has high response performance to
guarantee print quality, in addition, that support high peak current to run.
Note 5: When power supply cable is excessively long and small in diameter, the voltage drops
to cause error by wrong voltage sensing. To avoid this type of error, make sure to use
proper size of cable. The size recommended is less than AWG#18. If such a cable is
not available, connect the cable near the printer and place low ESR condenser
between 2200micro~6800 micro, capable of 35V voltage loading.

2) Change CN8 #1 pin LF to L, or set PWR on, holding Feed SW on operation panel. Set
PWR off to end.
2. For rewriting the flash ROM boot program; set both S-6 and S-2 on.
3. For rewriting flash ROM firmware; set S-6 on and S-2 off.
Important: Set S-6 off except for rewriting. If set it on, the program may be damaged.

2) Start and end of self print
Set the power switch on while FEED SW is being pressed, or release FEED button after
input of Reset signal to start self-print. It automatically stops with set patterns printed. While
self-print is under operation, printer status is in OFF LINE.

4.1.4 Paper sensor
The printer has a paper sensor located at each paper passing through section on the printer
mechanism to monitor no paper status. Once no paper status is monitored, it sends PE
signal to stop printing. Load paper once no paper status is found.

If any error stated above is detected, except communication error and paper near-end,
all operations stop and printer outputs /ERROR signal.
For parallel, /ERROR signal is changed to “L”.
For serial, /ERROR signal is changed to “L”.
Error bit of status information is set ON.
2) Return to normal status from error status
Remove causes of error status and turn the power on again or input the INIT signal
to return to normal. When this process is activated, at the time of power switch
turned off, the printer will be initialized, so that settings are required again.
If data remains in the buffer, it will be cleared. Attention should be paid.
4.3 Buffer full print
If there remains data in the buffer after one line of data is received, printer automatically
prints preceding data. The volume of buffer full data varies depending on ASCII characters or
bit images.
