Read carefully Before Using NP-255

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.

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 reliability.

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) Electrolyte 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 of 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.

10. When cleaning the printer with a vacuum cleaner, avoid the printer’s paper outlet from

locating cleaner’s air inlet.

11. The printer’s main structure parts use plated steel. However, rust may be caused to the cut

section.

12. Reflection type of infrared ray sensors is used at some locations in the printer. Direct sun

light may cause mal-function of printer. Avoid from such a location for installation.

13. This printer does not support any operations caused by the commands or control commands

not specified in this manual.

1. Overview

1.1 Overview

The printer is 2 inch, thermal and compact sized journal printer with easy operation by using the

newly designed “easy operation mechanism”. Furthermore, it is made in high speed and high

quality with auto-cutter attached, or high performance KIOSK printer unit.

1.2 Features

1) Paper replacement is made easy by using newly designed “easy operation mechanism.

2) Paper rewinding mechanism

3) High speed printing: 85mm/sec (for ASCII full digit print, excluding communication time) .

4) Center control at the host is available by uploading various types of preventive information.

5) Downloading the firmware is available by communication.

6) Possible to write “64K bytes x 3 “ patterns in flash ROM.

7) Emulation is in accordance with ESC/POS.

8) Windows Drivers (Windows 95/98/NT4.0/2000) are available.
